Though aluminum has low X-ray transmittance, the layer thickness is decreased and further the base material layer is formed by a polyimide having a high X-ray transmittance, thereby, the damping factor of X-ray passing through the X-ray passing window 44 can be remarkably reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sample storage container of an X-ray apparatus for storing a sample irradiated with X-rays in various states such as a high temperature state, a gas environment state and a vacuum state. .

[0002]

2. Description of the Related Art In an X-ray device such as an X-ray diffraction device,
When the sample is irradiated with X-rays, X-rays diffracted by the sample are detected by an X-ray detector. In this X-ray device,
Sometimes it is desired to observe the behavior of the sample under high temperature conditions. In addition, an inert gas such as helium may replace gas around the sample. Furthermore, the sample may be placed in a vacuum state for reasons such as preventing oxidation of the sample.

In order to satisfy the above-mentioned various conditions, a heater is built in, a gas introduction system is provided, and a sample is stored in a sample storage container equipped with a vacuum exhaust system. X-ray diffraction measurement is performed by irradiating the sample with X-rays. This type of sample storage container has an X-ray passage window in advance, and X-rays are introduced into the inside of the sample storage container through the X-ray passage window.

A conventional X-ray passage window is as shown in FIG.
It was formed by covering the opening 119 partitioned by the support 110 to the left and right with the shielding member 111. The shielding member 111 was usually formed of aluminum foil. Reference numeral 112 denotes a rib having a shape as shown in FIG. 9, which is brazed to the peripheral edge so as to cross the opening 119. The columns 110 and the ribs 112 are provided to prevent the shielding member 111 from being sucked into the casing 109 and deformed when the inside of the casing 109 is evacuated to a vacuum state. Since the aluminum foil is a material that is relatively flexible, the columns 110 and the ribs 112 were necessary to prevent the aluminum foil from being deformed.

[0005]

However, conventionally,
The aluminum foil used as the shielding member 111 has to have a considerably large thickness in order to maintain high mechanical strength, and as a result, X-rays passing through this shielding member 111. However, there was a problem that the intensity of the was greatly attenuated. Specifically, the attenuation rate was about 55%. Further, the passage of X-rays is blocked at the place where the columns 110 and the ribs 112 are provided, and as a result, the attenuation rate of X-rays may be further increased. The higher the attenuation rate of the X-rays passing through the X-ray passage window, the smaller the intensity of the X-rays that irradiate the sample stored in the casing 109, and thus the measurement accuracy of the X-ray measurement deteriorates. . The present invention has been made in view of the above problems, and an object thereof is to reduce the attenuation rate of X-rays passing through a sample storage container.

[0006]

A sample storage container of an X-ray apparatus according to the present invention includes a sample enclosing a sample and a sample storage window provided in the casing for passing X-rays. It is a container. The X-ray passage window has an opening formed in the casing and a shielding member that shields the opening. The shielding member is formed of a laminated material having a base material layer and a heat reflection material layer laminated on the base material layer. The shielding member is attached to the casing so that the heat reflection material layer is located on the inner surface side of the casing.

The base material layer maintains the mechanical strength exclusively so that the shielding member is not deformed. The heat-reflecting material layer reflects the heat inside the casing to prevent the heat from leaking to the outside. Since the heat-reflecting material layer does not need to exert the function of maintaining mechanical strength, its thickness can be made very thin. The heat-reflecting material layer is generally formed of a material that does not easily pass X-rays, and the fact that the thickness of the layer can be made thin means that the X-ray attenuation rate can be reduced accordingly.

The main role of the base layer is to maintain mechanical strength, and other properties can be freely selected. Therefore, a material having a low adiabatic effect but a high X-ray transmittance can be used. Thus, if a material having a high X-ray transmittance is used as the base material layer, the attenuation rate of X-rays passing through the X-ray passage window can be further reduced.

The base material layer having such a high X-ray transmittance can be formed of, for example, a polyimide film. This polyimide film is, for example, the product name Kapton (Toray
It can be realized by a film provided by DuPont Co., Ltd.). The base material layer may be transparent or non-transparent, but it is desirable to form the base material layer with a transparent material in order to prevent heat from being trapped inside the shielding member. Since the polyimide film is usually transparent, it is suitable as a base material layer also from this point.

As the heat reflecting material, aluminum, gold,
A material such as silver that can reflect heat and has a high melting point can be used.

According to an experiment by the present inventor, a transparent polyimide film (trade name Kapton) is used as a base material layer, aluminum is vapor-deposited on the base material layer to form a heat reflection material layer, and a laminated film is formed. When used as a shielding member for an X-ray passage window, the X-ray attenuation rate was about 55% in the conventional sample storage container in which the shielding member was formed of a single aluminum foil. Was significantly reduced to about 7%.

If the shielding member is made of a laminated film as in the present invention, by appropriately selecting the base material layer, for example, by selecting a polyimide film,
High mechanical strength can be obtained even at high temperatures. Further, if the shielding member is adhered to the periphery of the opening formed in the casing for passing the X-rays, it is possible to prevent the shielding member from being drawn into the casing and deformed even if the inside of the casing is in a vacuum state. . As a result, according to the present invention, it becomes unnecessary to reinforce the shielding member 111 by using the columns 110 and the ribs 112 as in the conventional example shown in FIG. 8, and the opening for X-ray passage does not have a single shape. It can be a hole. By doing so, the situation in which the progress of the X-rays passing through the portion is blocked by the support columns 110 and the ribs 112 is eliminated, so that the attenuation rate of the X-rays can be further reduced.

[0013]

FIG. 6 schematically shows a case in which the sample storage container according to the present invention is installed in an X-ray diffraction apparatus as an X-ray apparatus. This X-ray diffraction apparatus has an X-ray source F, a goniometer 1, and an X-ray detector 2. X-ray source F

The goniometer 1 is a sample 3 to be measured.
I support. Further, the goniometer 1 rotates the sample 3 intermittently or continuously at a predetermined angular velocity around the rotation center axis line L passing through the X-ray incident surface of the sample 3, so-called θ rotation,
At the same time, the X-ray detector 2 is rotated in the same direction at an angular velocity twice the θ rotation, that is, the so-called 2θ rotation. A goniometer in which the plane containing the rotation trajectories of θ rotation and 2θ rotation is a horizontal plane is generally called a horizontal goniometer, and a goniometer in which that plane is a vertical plane is a vertical goniometer.
It is called a sample horizontal type goniometer.

When irradiating X-rays on the sample 3 rotating by θ,
When the Bragg diffraction condition is satisfied between the X-ray and the crystal lattice plane of the sample 3, X-ray diffraction occurs on the crystal lattice plane. This diffracted X-ray is detected by the X-ray detector 2,
Based on the detection result, the relationship between the diffraction angle of the diffracted X-ray and the X-ray intensity is obtained. And from this relationship, sample 3
Various properties of the are determined.

The sample 3 is stored inside a sample storage container 4 fixed on the goniometer 1. The sample storage container 4 is used for the purpose of maintaining the sample 3 in a vacuum state at a high temperature and, if necessary, performing gas replacement around the sample 3 with helium or another inert gas. The reason why the sample is kept at a high temperature is to observe the behavior of the sample at a high temperature. Also, maintaining a vacuum state is
This is mainly to prevent oxidation of the sample when placed in a high temperature state.

As shown in FIG. 1, the sample storage container 4 has a casing base 5 fixed on the goniometer 1, a cylindrical casing side wall 6 fixed on the casing base 5, and a screw 7. A casing-pair base wall 8 fixed on the casing side wall 6. The casing base 5, the casing side wall 6, and the casing-pair base wall 8 are made of a material that is light and difficult to transfer heat, such as aluminum, and are hermetically assembled to each other to form a casing 9 that surrounds the sample 3. doing.

Inside the mounting base 13 of the casing base 5, inside the casing side wall 6 and casing-to-base wall 8
A cooling liquid passage 10 is formed inside each of the parts, and a cooling liquid, for example, cooling water introduced through the cooling liquid introduction port 15 flows through these passages 10 to cool the entire casing 9, and the casing 10 is Prevents high temperature. Further, a gas introduction port 20 is provided on the surface of the casing side wall 6 opposite to the X-ray passage opening 39, and if necessary, an inert gas such as helium gas is introduced into the casing 9 through the gas introduction port 20. Introduced, which allows sample 3
Is replaced with gas.

The casing base 5 has a fixed base 11 fixed to the goniometer 1 and a movable base 12 arranged on the fixed base 11 so as to be slidable in the left-right direction.
And a mounting base 13 fixed on the movable base 12.
And is constituted by. The casing side wall 6 is fixed on the mounting base 13. A drive shaft 16 rotatably supported by a bearing 14 so as not to move in the axial direction is penetratingly provided at an appropriate position of the movable base 12, and a screw 16a formed at the tip of the drive shaft 16 is fixed to the fixed base 11. It meshes with the screw 17.

A gear 18 fixed to the middle portion of the drive shaft 16
Engages with an output shaft 21a of a motor 21 fixed on a bracket 19 extending from the movable base 12. A wheel 22 for detecting the rotational angle position of the drive shaft 16 is fixed to the rear end of the drive shaft 16.
An optical sensor 23 for detecting is detected. When the motor 21 operates, the drive shaft 16 rotates, and at this time, the movable base 12 moves in parallel to the left and right due to the engagement of the screw 16a and the screw 17. The position of the sample 3 is adjusted by this parallel movement. The output shaft 21a of the motor 21 can be manually turned by turning the knob 24, whereby the position of the movable base 12 can be adjusted.

A cylindrical exhaust port 25 is provided in the center of the casing-to-base wall 8 by a bearing 26 so as to be rotatable about the rotation center axis L of the sample 3 but not axially movable. The rubber O-ring 28 maintains airtightness around the exhaust port 25. When the knob 29 screwed to the tip of the exhaust port 25 is loosened and removed, and an exhaust hose 31 is connected instead of the knob 29, the inside of the casing 9 is exhausted through the exhaust hose 31 to bring the part into a vacuum state. be able to.

A disc-shaped mounting plate 32 is fixed to the center of the mounting base 13, and a furnace unit 33 is fixed on the mounting plate 32 by screws or other fasteners. Further, the entire furnace body unit 33 is covered with a heat insulating cylinder 34 formed by molding cotton-like alumina into a substantially cylindrical shape. The sample 3 is kept at a constant temperature by the heat insulating cylinder 34. As shown in FIG. 5, a locking piece 36 and a receiving plate 37 are provided at appropriate positions on the inner peripheral surface of the casing side wall 6. On the other hand, a square hole ring member 38 is provided at the upper end of the heat retaining cylinder 34. When the heat retaining cylinder 34 is inserted into the casing side wall 6, the locking piece 36 enters the square hole ring member 38, and the lower end of the heat retaining cylinder 34 is received by the receiving plate 37.

As described above, since the heat retaining tube 34 is fixedly supported inside the casing side wall 6 by fitting the locking piece 36 and the square hole ring member 38, the sample storage container 4 is moved in accordance with the movement of the goniometer 1. Insulation tube 3 even when moving
The position of the sample 4 does not shift or move unstablely inside the casing 9, so that the sample 3 can always be stably held.
Further, not only when the casing 9 is fixed on the horizontal surface, but also when the casing 9 is fixed on the vertical surface, that is, when the casing 9 is supported in the horizontal direction, the heat insulating cylinder 34 is stabilized at a fixed position with respect to the casing 9. Can be supported. That is, the sample storage container 4 of the present embodiment can be used without problems for both a horizontal goniometer whose mounting surface is a horizontal surface and a vertical goniometer whose mounting surface is a vertical surface.

As shown in FIG. 4, an elongated hole-shaped opening 39 is formed over a predetermined angular range in the circumferential direction of the casing side wall 6, for example, an angular range of about 180 °.
Is covered with a shielding member 41 to be shielded from the outside, and the upper and lower sides of the shielding member 41 are pressed against the casing side wall 6 by a ring-shaped band 42. Thus, the opening 39 and the shielding member 41 covering the opening 39 allow X
An X-ray passing window 44 for passing a ray is configured. Desirably, adhesive members 43 are provided on the upper and lower peripheral edges of the opening 39, and the shielding member 41 is adhered to the casing side wall 6 by these adhesive members. As the adhesive member 43, a double-sided adhesive tape, an adhesive or the like can be used. By adhering the shielding member 41 to the casing side wall 6 in this way,
Even when the inside of the casing 9 is in a vacuum state, the shielding member 41 can be prevented from being deformed so as to slip inward.

As shown in FIG. 7, the shielding member 41 is a base material layer 41 formed of a transparent polyimide film, for example, Kapton (trade name, manufactured by Toray DuPont Co., Ltd.).
It is formed as a laminated film by depositing aluminum on a and laminating the heat reflection material layer 41b. The shielding member 41 is adhered to the casing side wall 6 by the adhesive member 43 so that the heat reflection material layer 41b faces the inner surface of the casing 9.

The polyimide film used as the base material layer 41a has a wide temperature range from low temperature to high temperature.
It has no air permeability and has mechanical strength to the extent that the vacuum inside the casing 9 can be maintained, and has a significantly higher X-ray transmittance than aluminum. The aluminum used as the heat-reflecting material layer 41b reflects the heat inside the casing 9 to prevent it from escaping to the outside. Although aluminum itself does not easily transmit X-rays, in the present embodiment, since it is made extremely thin by vapor deposition, the amount of attenuation of X-rays passing through the shielding member 41 is very small.

In FIG. 6, X emitted from the X-ray source F
The rays are introduced into the inside of the sample storage container 4 through the X-ray passing window 44 including a shield member having a two-layer structure composed of the base material layer and the heat reflection material layer, and are irradiated to the sample 3, and further the diffraction generated in the sample 3 is generated. The X-rays pass through the X-ray passing window 44 and the sample storage container 4
To the outside and detected by the X-ray detector 2. As shown in FIG. 4, the opening 39 is long in the circumferential direction, but no columns or ribs are provided therein. That is, the opening 39 is formed as a single-shaped hole having no partition. If a column or a rib is provided somewhere in the opening 39, the column or the like interferes with the passage of X-rays.
There is a risk of attenuating the intensity of the X-rays incident on the sample and the X-rays diffracted by the sample. On the other hand, according to the present embodiment having no such columns, it is possible to surely prevent X-ray attenuation over a wide angle range regarding the θ rotation of the sample 3 and the 2θ rotation of the X-ray detector 2.

The furnace body unit 33 disposed inside the casing 9 is, for example, as shown in FIG.
6 and a cylindrical outer tube 47 arranged on the base 46 thereof.
A sample support column 49 that supports the sample container 48, and a cylindrical inner tube 52 disposed below the sample support column 49 and between the sample support column 49 and the outer tube 47. There is. FIG.
As shown in FIG. 5, the sample 3 to be measured is packed in the sample container 48, and the sample container 48 is further inserted in the support frame 49 a of the sample support column 49.

A screw 49 is attached to the lower end cylindrical portion of the sample support column 49.
b is formed, and the threaded portion 49b is formed by the inner tube 52,
The bottom portion 47 a of the outer tube 47, the cylindrical collar 51, and the base 46 project through the base 46 to the opposite side, and the protruding portion is fastened to the bottom surface of the base 46 by the nut 53. The upper end of the outer tube 47 is shielded from the outside by the disk-shaped lid 54. In this way, the sample 3 is placed at a predetermined position on the sample support column 49, and the entire sample support column 49 is housed inside the outer tube 47. Further, by fixing the furnace body unit 33 containing the sample 3 to the mounting plate 32 in the casing 9 in FIG. 1, the sample 3 can be placed at a predetermined position inside the sample storage container 4.

In FIG. 3, an elongated hole 55 for X-ray passage is formed over an appropriate angular width of the outer tube 47 in the circumferential direction, for example, an angular width of 180 °. A single heating wire 56a is wound in the longitudinal direction, that is, the axial direction, on both the outer surface and the inner surface of the outer tube 47. Heating wire 56a
Is wound in the vertical direction with respect to the outer tube 47, so that the slot 55
Therefore, the front surface of the sample 3 is largely opened by the elongated hole 55. Therefore, the X-rays incident on the sample 3 and the X-rays diffracted by the sample 3 are not attenuated by being hindered by the outer tube 47, the heating line 56a, and the like.

A heating wire 56 is provided on almost the entire surface of the sample support column 49.
b is wound in the lateral direction. A heating wire 56c is also wound around the outer peripheral surface of the inner tube 52 in the lateral direction, that is, in the circumferential direction. Each of the heating wires 56a, 56b and 56c is formed of, for example, platinum. Each heating wire generates heat when energized, and heats the sample 3 from both front and back surfaces.

The operation of the X-ray storage container 4 having the above structure and the X-ray diffraction apparatus using the same will be described below. First, the sample 3 is mounted in the furnace body unit 33 as shown in FIG. 3, and the furnace body unit 33 is put and fixed in the casing 9 as shown in FIG. At this time, as for the casing 9, the casing side wall 6 is attached to the casing base 5, and the casing-to-base wall 8 is not yet attached to the tip of the casing side wall 6. That is, the tip of the casing 9 is an open end, and the furnace body unit 33 is inserted from the open end.

Thereafter, as shown in FIG. 5, the heat insulation cylinder 34 is inserted into the inside of the casing side wall 6, and the square hole ring member 38 and the locking piece 36 are firmly fitted to stabilize the heat insulation cylinder 34. Support the state. Since the lower end portion of the heat insulating cylinder 34 is received by the receiving plate 37, it is always placed in a stable state. After that, the casing-to-base wall 8 is placed on the tip of the casing side wall 6 and fixed by the screw 7, and the exhaust hose 31 is connected to the tip of the exhaust port 25. Although not shown, an exhaust device such as a vacuum pump is connected to the other end of the exhaust hose 31.

After the sample 3 is placed at a predetermined position in the X-ray container 4, the X-ray container 4 is fixed on the goniometer 1 of the X-ray diffraction apparatus. Then, the inside of the casing 9 is exhausted through the exhaust hose 31, the heating wires 56a, 56b, 56c (see FIG. 2) are energized to heat the sample 3, and the cooling liquid is introduced through the cooling liquid inlet 15. To cool the casing 9. Further, gas is introduced into the inside of the casing 9 through the gas introduction port 20 as needed. When the temperature around the sample 3 inside the casing 9 is set to a desired high temperature and a vacuum state is set, the X-ray diffraction measurement is started.

That is, on the X-ray optical path from the X-ray source F to the X-ray detector 2, including placing the sample 3 at an appropriate position in terms of X-ray optics by operating the motor 21. The optical positions of various X-ray optical elements arranged in the above are set to appropriate positions. After that, in FIG. 6, the sample 3 is rotated by θ by the goniometer 1, and at the same time, the X-ray detector 2 irradiates the sample 3 with X-rays emitted from the X-ray source F while rotating the X-ray detector 2 by 2θ at an angular velocity twice as high. When diffracted X-rays are generated in the sample 3, the diffracted X-rays are detected by the X-ray detector 2. When the X-ray diffraction measurement is performed in this way, the casing 9 rotates integrally with the θ rotation of the sample 3,
The exhaust port 25 provided in the counter base wall 8 is formed in a cylindrical shape around the rotation center axis L of the sample 3 and is rotatable about the axis L, so that the casing 9 rotates. However, the exhaust port 25 and the exhaust hose 31 connected to the exhaust port 25 always remain in the same position without rotating. This can prevent the exhaust hose 31 from rotating around and twisting.

In this embodiment, as shown in FIG.
The shielding member 41 is composed of a base material layer 41a made of a polyimide film and a heat reflecting material layer 41b made of aluminum laminated on the base material layer 41a.
Since b is located on the inner surface side of the casing 9, it is possible to reliably prevent heat from leaking to the outside of the casing 9 by the heat reflection of the heat reflection material layer 41b, and moreover, the heat reflection material layer 4b.
By making the thickness of 1b as thin as possible, the attenuation rate of X-rays passing through the shielding member 41 can be significantly reduced. As a result, in FIG. 1, the sample 3 can be irradiated with a strong X-ray, and the diffracted X-ray from the sample 3 can be taken out of the casing 9 without being attenuated.

Although the present invention has been described above with reference to the preferred embodiments, the present invention is not limited to the embodiments and can be variously modified within the technical scope described in the claims. For example, the present invention is not limited to X-ray diffractometers, but can be applied to any X-ray device that requires a casing to store a sample to be irradiated with X-rays. Further, a structure other than the structure related to the X-ray passage window, for example, the casing 9
With respect to the structure of No. 1 and the structure of the furnace unit 33, any structure other than the illustrated structure can be used.

The base material layer 41a is preferably formed of a polyimide film, but is a material having a high mechanical strength to the extent that a vacuum state can be maintained and having a higher X-ray transmittance than aluminum or the like. It is also possible to use other arbitrary materials as long as they are provided. The heat-reflecting material layer 41b can also be formed of gold, silver or the like other than aluminum.

[0039]

According to the sample storage container of the X-ray apparatus of the first aspect, the mechanical strength of the shielding member is ensured by the base material layer, and at the same time, the heat reflection that heat leaks to the outside of the casing. It can be reliably blocked by the material layer. Then, by making the thickness of the heat-reflecting material layer as thin as possible, the attenuation rate of X-rays passing through the shielding member can be remarkably reduced as compared with the conventional product in which the shielding member is made thick with a single layer of aluminum foil. . This makes it possible to irradiate the sample with high-intensity X-rays, and further to guide the X-rays diffracted by the sample to the X-ray detector without attenuating.

According to the sample storage container of the X-ray apparatus of the second and third aspects, the heat-reflecting material layer can be formed very thin and uniform in thickness. Furthermore, it is possible to impart high mechanical strength and high X-ray transmittance to the shielding member within a wide temperature range.

According to the sample storage container of the X-ray apparatus of the fourth aspect, it is possible to prevent heat from staying inside the shielding member.

According to the sample storage container of the X-ray apparatus of the fifth aspect, since no support pillars or ribs are provided in the X-ray passage opening, the dead angle is large even when the diffraction angle 2θ is wide. The diffracted X-ray can be detected at each diffraction angle without causing
