Definitions
- the present invention relates to a polycabilization which is an optical element that collects or collimates X-rays.
- one of X-ray optical elements is formed into a columnar shape by bundling a large number of thin tubes, and the X-rays incident from the incident end face are converted into the thin tubes.
- Various characteristics are obtained by the arrangement of the narrow tubes, and if the output end face side is gradually narrowed, parallel light can be collected, and if the incident end face side is gradually narrowed, the divergent light is parallelized. If it is configured so that both are gradually reduced, divergent light can be emitted.
- Poly-Oil material is mainly composed of Si O from the viewpoint of processability and total reflection characteristics.

- X-rays having a shorter wavelength (higher energy) than incident X-rays of the target wavelength to be collected or collimated pass through the narrow tube and go straight.
- the sample may be irradiated with collimated X-rays, which may adversely affect the analysis by, for example, exciting unnecessary fluorescent X-rays or increasing the background.
- the present invention has been made in view of the above-described conventional problems, and in a polycylinder, an adverse effect on analysis by X-rays having higher energy than that of focused or parallel X-rays can be removed.
- the purpose is to provide.
- the first configuration of the present invention is formed in a columnar shape by bundling a large number of thin tubes, and proceeds while totally reflecting X-rays incident from the incident end face in the thin tubes.
- the X-rays that pass straight through the narrow tube with higher energy than the X-rays that are collected or paralleled out of the incident X-rays are collected or parallel. Separated from X-rays.
- the condensed or parallel X-rays travel in the direction of the curved axis, whereas the higher-energy X-rays travel straight through the narrow tube.
- the two can be separated spatially so that they do not irradiate the same location. Therefore, the adverse effects on analysis by high-energy X-rays compared to focused or parallel X-rays can be eliminated.
- a large number of thin tubes are bundled to form a columnar shape, and the X-rays incident from the incident end surface travel while being totally reflected in the narrow tube, and are emitted and collected by the output end surface force.
- a shielding plate that covers a part of the incident end face and does not transmit X-rays can be used to collect or collimate the incident X-rays. X-rays traveling straight through the narrow tube with higher energy than the X-rays to be separated are separated from the condensed or collimated X-rays.
- a portion of the incident end face is covered with a shielding plate that does not transmit X-rays, so that the X-rays that are condensed or collimated can travel in the direction in which the X-rays travel with higher energy. It is possible to prevent the X-rays traveling straight through and from traveling, and to separate them from each other so that they do not irradiate the same place. Therefore, it is possible to eliminate the adverse effects on the analysis by high-energy X-rays rather than X-rays that are focused or parallel.
- a large number of thin tubes are bundled to form a columnar shape, and the X-rays incident from the incident end surface travel while being totally reflected in the narrow tube, and are emitted and collected by the output end surface force.
- a parallel parallel cylindrical having a columnar shielding portion that extends from a part of the incident end face to a part of the exit end face and does not transmit X-rays, the out of the incident X-rays X-rays that travel straight through the narrow tube at a higher energy than X-rays that are condensed or collimated are separated from the X-rays that are converged or collimated.
- the partial force of the incident end face extends to a part of the exit end face, and has a columnar shielding portion that does not transmit X-rays.
- X-rays travel straight through the narrow tube with higher energy. Can be prevented, and both can be spatially separated so as not to irradiate the same place. Therefore, it is possible to eliminate the adverse effects on the analysis by high-energy X-rays compared to focused or parallel X-rays.
- the first to third structures of the polycillaries are housed in a cylindrical shielding case that covers its side surface, the periphery outside the entrance end surface and the periphery outside the exit end surface and does not transmit X-rays. Then, a poly-cabilizer reset may be used. With such a poly-carbilla reset, it is possible to prevent the X-ray from traveling into the shielding case even if X-rays are irradiated outside the incident end face, and to pass straight through the narrow tube with high energy. Can also be prevented from proceeding out of the shielding case, eliminating the negative effects of high-energy X-ray analysis.
- FIG. 1 is a schematic diagram showing a poly resetter according to a first embodiment of the present invention.
- FIG. 2 is a schematic diagram showing a polycabilizer reset according to a second embodiment of the present invention.
- FIG. 3 is a schematic diagram showing a poly-cabilizer reset according to a third embodiment of the present invention.
- this poly-crystal reset 10A is one in which a poly-chiral (main body) 1A is housed in a shielding case 2A (showing a longitudinal section).
- a large number of thin tubes with a glass power consisting mainly of 2 are bundled to form a cylindrical shape, and the diameter decreases gradually toward both the incident end face 1A a side and the outgoing end face lAb side. It is configured as follows. Therefore, the X-ray 4 that diverges from the point light source 3 and enters the incident end face lAa is made to travel while being totally reflected in the narrow tube and is emitted from the exit end face lAb, and the emitted X-ray 5 is collected at the condensing point 6. Shine.
- the shielding case 2A that accommodates the poly-pillar 1A is made of a material that does not transmit X-rays, such as stainless steel, and has a cylindrical shape that is coaxial with the poly-pillar 1A and has a constant diameter.
- Side surface, outer periphery from the incident end face lAa (annular surface extending from the outer edge of the incident end face lAa) and the outgoing end face lAb also covers the outer periphery (ring-shaped surface extending from the outer edge of the emission end face lAb).
- the X-ray 5 of the target wavelength to be collected travels in the direction of the curved axis 8, whereas the X-ray 5 of the target wavelength
- X-rays 7 with short wavelengths (high energy) pass straight through the narrow tube, they only travel within the range between the two-dot chain lines in Fig. 1, so they are even more than the upper limit of the range. It is spatially separated from the X-ray 5 focused on the upper focusing point 6 and is not irradiated at the same location. Therefore, it is possible to eliminate the adverse effect on the analysis by the X-ray 7 having higher energy than the X-ray 5 to be collected.
- this poly-crystal reset 10B is different from the poly-pillar reset 10A (FIG. 1) of the first embodiment in configuration in that the poly-cylindrical 1B and the shielding case 2B are not curved, and the incident end face IBa Since the only difference is that it has a shielding plate 9 that is a stainless steel disc, for example, which covers a part (here the central part) and does not transmit X-rays.
- the same reference numerals are given and description thereof is omitted.
- the X-ray 5 having the target wavelength to be collected is in the direction of the axis of the first axis (not shown! In other words, it travels in the right direction in Fig. 2, whereas X-ray 7 with shorter wavelength (high energy) than X-ray 5 with the target wavelength passes through the narrow tube and goes straight through the two-dot chain line in Fig. 2. Because the force does not advance in the two upper and lower ranges sandwiched between the X-ray 5 that converges on the condensing point 6 between the two ranges in the vertical direction in Fig. 2, it is spatially separated and the same place Is not irradiated. Therefore, X-rays to collect light 5 It is possible to remove the adverse effects on the analysis by X-ray 7 of Kogaku Nergi.
- this action and effect is obtained by storing in the force shielding case 2B that can be obtained only by the polycylinder 1B that is not covered by the shielding case 2B.
- the negative effects on analysis by high-energy X-rays can be removed more reliably.
- the polycrystal reset 10C is a part of the incident end face ICa (in this case, instead of the shielding plate 9). Since the only difference is that it has a cylindrical shielding part 11 made of lead glass, for example, which does not transmit X-rays, extending from the center part) to a part of the emission end face lCb (here central part). The same reference numerals are used for the numerals, and the description is omitted.
- Polycylinder 1C in this set 10C can be manufactured by using a thin column made of lead glass as the shielding part 11 as the central part when bundling a large number of thin tubes with glass power into a cylindrical shape. .
- the X-rays 5 of the target wavelength to be collected are in the direction of the axis (the central axis not shown) of the polycylinder 1C, that is,
- the X-ray 7 having a shorter wavelength (high energy) than the target wavelength X-ray 5 is sandwiched between the two-dot chain lines in Fig. 3 even if it travels straight through the narrow tube. Since it travels only in the two upper and lower ranges, it is spatially separated from the X-ray 5 focused on the condensing point 6 between the two ranges in the vertical direction in Fig. 3 and is not irradiated to the same place. . Therefore, it is possible to eliminate the adverse effect on the analysis by the X-ray 7 having higher energy than the X-ray 5 to be collected.

- the present invention is not limited thereto, and only the incident end face side is gradually increased.
- the present invention can be applied to both a polycillaries configured to squeeze and collimate the diverging light, and to a polycillaries configured to squeeze only the exit end face side and collect parallel light.
- the polycylinder, the shielding portion is a columnar shape
- the shielding case is a cylindrical shape
- the shielding plate is a circular plate, but other shapes may be used in the present invention.
