Definitions
- the present invention relates to the field of sample analysis by X-ray scattering.
- It relates in particular to a collimation device for an X-ray beam, an optical device for the analysis of a sample by X-ray scattering comprising this collimation device and a collimator for such a beam.
- X-ray beam means a photon beam whose energy is between 1 keV and 30 keV.
- the invention relates to the field of the analysis of a sample by X-ray scattering at small angles.
- small-angle scattering it should be understood that the rays scattered by a sample traversed by the beam (perpendicular incidence) to be analyzed are in the vicinity of the X-ray beam through which the sample is illuminated, in an angle generally between 0 , 1 ° and 10 ° with respect to the optical axis of the beam.
- FIG. 1 An optical device known for implementing a SAXS technique is shown in FIG. 1, in an exploded perspective view.
- the device comprises an X-ray source.
- the beam 1 generated by the source 10 is then directed to a monochromator mirror 11, which makes it possible to produce a monochromatic beam, that is to say containing only one wavelength of X-rays. that a beam is monochromatic when the ratio between the wavelength difference and the desired wavelength is less than 1%.
- the beam has a preferential axis of propagation called "optical axis". Transversally to the optical axis, the beam has a quasi-uniform section when so-called “collimating” mirrors are used, or converging towards a distant point when mirrors called “convergent” are used.
- geometric definition of the beam at the output of the monochromator is not sufficient to perform small angle scattering experiments.
- geometric definition we mean the real difference between a geometry of the beam (parallel or convergent) perfect and that which is physically obtained.
- obstacle an opaque X-ray device at the wavelength employed.
- the first "obstacle” generally corresponds to four opaque mobile X-ray lips, referenced 12.
- Two parallel lips with a spacing D in the plane perpendicular to the axis of the beam define a "slit”. ".
- a collimator is also generally formed of two “holes” whose centers must be aligned with the optical axis of the beam coming out of the monochromator.
- the first obstacle in the form of a plate 12 provided with two pairs of lips forming these two slots, thus forms a hole.
- the plate 12 provided with the two pairs of "lips" can be integrated in the mirror 1 1.
- the plate 12 is generally followed by a calibrated attenuator
- the beam is then directed to a second obstacle for collimation, placed at a distance from the first obstacle along the optical axis of the beam.
- This second obstacle is also in the form of a plate 13 having two pairs of parallel lips, to form two slots whose centers are aligned with the optical axis of the beam.
- optical path between the two sets of collimation "slots" can be evacuated. Sometimes, it may, alternatively, be placed in a helium atmosphere.
- the coupling of the two collimation means 12 and 13 makes it possible to define the size of the beam that it is desired to obtain at the level of the sample 16.
- the beam passes through a third pair of slots 15, which are placed along the optical axis just before the sample 16 to be analyzed.
- These so-called “anti-scattering” slots do not, properly speaking, be part of the collimator. Indeed, the anti-scattering slots 15 make it possible to eliminate the parasitic diffusions produced by the slots of the collimation means 12 and 13.
- Adjusting the anti-scattering slots 15 is particularly delicate, since it is necessary to brush the beam without touching it to eliminate spurious broadcasts without changing the size of the beam.
- the interaction of beam 1 with sample 16 causes X-ray scattering, the beam being further transmitted at least partly through the sample.
- the transmitted beam and the diffused part are then accommodated in a second vacuum chamber 18 at the end of which is a means 19 for stopping the beam.
- the vacuum chamber makes it possible to limit both the additional absorption by the air, the scattered rays and the complementary diffusion of the beam 1 always by the air.
- the plate 12 provided with collimation slots (first obstacle)
- the plate 13 also provided with collimation slots (second obstacle) and anti-scattering slots 15, without which it would be difficult to detect the X-rays scattered by the sample, in particular the small-angle scattered rays located near the optical axis of the beam.
- the relative position of the different obstacles 12, 13 and 15 is also important for this purpose.
- these obstacles 12, 13, 15 are generally four independent lips forming rectangular or square slots. These lips are provided with blades that can be moved to adjust the dimensions of a slot. These blades are metal and usually made of steel, tantalum or made of tungsten rods.
- a blade 21 at a slot is for example shown in Figure 2, in a sectional view. Conventionally, such a blade 21 has a thickness of approximately 1.5 mm.
- monocrystalline structure blade By monocrystalline structure blade, it should be understood that the material forming the blade is made of a single solid material having a elementary mesh repeating itself in a regular way, to finally form an ordered structure.
- Such a hybrid blade comprising a metal blade 21 and a monocrystalline structure blade 22 is for example shown in Figure 3, according to the same sectional view as Figure 2.
- the slots provided with these blades thus make it possible to improve the quality of the device.
- the monocrystalline structure which is placed at the edge of the blade returns the X-rays at well-defined angles which depend on the crystalline plane of this structure. These angles are large enough not to be confused with the beam.
- the hybrid slot however, has a more complicated structure than the metal slits.
- the displacement of the blades is also more complex, especially if the slots are made to be installed under vacuum or in a controlled atmosphere, such as helium (He).
- An object of the invention is to provide a simplified optical device and comprising at least one collimation device of an X-ray beam having the advantages of a hybrid slot without presenting at least one of the disadvantages.

- An alternative embodiment may consist in replacing the assembly formed by the collimating means 13 and the anti-diffusion slots 15 of the optical device according to the prior art shown in FIG. 1 by a plate 104 according to the invention.
- This plate 104 is then disposed at the outlet of an enclosure intended to be under vacuum (or in a controlled atmosphere), as shown in FIG. 6, in order to form an X-ray collimation device.
- this enclosure does not comprise a plate according to the invention at its input, but this input is preceded by the slots 12 and, where appropriate, the calibrated attenuator (not referenced) as shown in Figure 1.
- an X-ray beam collimator comprising a plurality of plates made of a monocrystalline material, contiguous to each other so that said at least one opening of each plate widens between the upstream face and the downstream face. of the plate or the opposite.

- the thickness and plate encountered by the beam 200 is low at the contour of this opening.
- the collimation of the beam 200 is thereby improved by transmitting only the beam passing through the space E left by the opening, on the upstream side of the plate.
- the plate is made of silicon.
- germanium which is a denser material than silicon, this arrangement will be of particular interest for the X-ray energy range of 15keV to 30keV.
- the applicant made measurements and made some calculations.
- joining plates can be envisaged at each end of the enclosure 110 shown in FIG. 5. This can also be envisaged only at the entry or only at the exit of this enclosure 1 10, in particular if only this output comprises a plate 104 according to the invention.
- this opening 104C is thus similar to that obtained by joining a plurality of plates 104, as represented in FIG. 7.
- the plate 104, 104 'used in the context of the invention finally has several advantages over a hybrid slot as presented in document D1. Indeed, the structure is simple, made of a single crystal. In addition, this plate will most often be attached to the ends of a vacuum chamber or controlled atmosphere, so that the manipulator will not be made to make adjustments: the only adjustment is the initial positioning of the plate. In addition, the generally used manufacturing process, chemical, generates an excellent surface state, which limits the risks of spurious broadcasts.
