That is, the charged particles emitted from these charged particle generators 8 strike an optical element (evening) 6 having a condensing or diverging function to generate radiation. Further, as the charged particle circulating device of the present invention, an electron storage ring, a betatron, a microtron, a synchrotron, or the like can be used. That is, the optical element 6 is inserted into the orbit of these charged particle orbiting devices to generate radiation.

Converge or diverge at the same time. Conventionally, these X-ray optical elements have been used to collect and diverge X-rays by applying them to the generated X-rays. Since conventional X-ray optical elements are placed away from the light source, only a portion of the generated X-rays can be collected. There are transition radiation or coherent transition radiation targets as X-ray generation elements, but these elements can be considered as X-ray optical elements in the sense that they generate directional divergent light. A single crystal can be thought of as an optical element in the sense that it collects X-rays of specific energy as a diffraction spot.
- X-ray optical element such as a Fresnel zone plate, a diffraction grating, and an
- the Fresnel zone plate is generally composed of a concentric pattern, and the cross section is uneven as shown in FIG.

- S i N a material that easily transmits X-rays.
- S i N a material that easily transmits X-rays.
- the width and spacing of the irregularities are determined by the Bragg condition, and the relationship with the focal length is determined by the converged wavelength as in the conventional theory, but the thickness of the convex part is different from the conventional one.
- the conventional Fresnel zone plate for X-rays has a thickness necessary for absorbing the target X-rays.
- the target X-rays are generated. It becomes the necessary thickness. If it is too thick, there is a problem that the target X-rays are absorbed and do not pass through. However, if it is too thin, there is a problem that the generation efficiency of X-rays decreases.
- tantalum or the like is conventionally suitable for the material, but various materials are used in the embodiment of the present invention.
- a 1 in the range of 10 to 50 microns is appropriate, and in the case of 30 keV, 10 to 50 micron Cu, 1 In the case of ke V, Be of a few micron to 50 microns is appropriate.

- the target X-ray energy-higher. Therefore, it may be several 10 keV or several MeV.
- the electron energy is low, there is a problem that the target generates heat due to the absorption of electrons. If the energy is high, electrons are transmitted.
- the higher the energy the higher the circulating efficiency. In general, 1 MeV or more is appropriate for electronic energy.
- the convex portion 15 of the Fresnel zone plate is made of Sn (Be, Zn, Ga, Pt, Pb, Bi, and other substances having a high plasma frequency. ) and Mg (vacuum, B e, a l, a l 2, ⁇ 3, C, B e, S i N, in combination with low substance) of S i C other plasma frequency, alternately about 1 0-layer It is to be used by stacking.
- each layer at that time is determined by the theory of coherent controlled radiation. For example, when Sn and Mg are combined and 20 MeV is used for electron energy, the thickness of 311 is 0.5 microns and the thickness of Mg is about 7 microns.
- the third embodiment of the present invention is a case where the same Fresnel zone plate as that used as a conventional X-ray optical element is used. That is, as shown in Figure 5. This is the case with a normal pattern.
- a membrane with high X-ray generation efficiency is used as the membrane 11 which is an X-ray emitter. Tantalum, platinum, lead, tungsten, bismuth, etc. should be used for the convex part of the pattern.

- Transition radiation is significant for obtaining divergent light, and can place high-intensity quasi-monochromatic X-rays by placing them in the orbit of a charged particle orbiting device.
- the fifth embodiment of the radiation generating apparatus of the present invention is a case where a diffraction grating is used for X-ray targeting.
- the diffraction effect of both diffraction gratings and Fresnel zone plates is Bragg's diffraction theory, with uneven patterns arranged alternately in a line.
- the material of the pattern of the convex part and the material of the membrane are as described in the Fresnel zone plate.
- the sixth embodiment of the radiation generating apparatus of the present invention is a case where a lens having a predetermined curvature is used as the X-ray target.
- the substance has a predetermined refractive index for X-rays as well as visible light. However, its refractive index is smaller than 1 and 0.99 9 different from visible light. And the denser the element, the smaller. For this reason, a visible convex lens acts as a concave lens in X-rays, and a concave lens acts as a convex lens. Designing the curvature based on the refractive index to determine the focal length is no different from designing an ordinary optical lens. However, again, the material selection
- the seventh embodiment of the radiation generating apparatus of the present invention is a case where crystals are used. Use crystals instead of Fresnel zone plates. Therefore, when a crystal is put into an electron orbit, bremsstrahlung or characteristic X-rays are generated from atoms in the crystal lattice, and diffraction is caused by the crystal to emit X-rays of specific energy in a specific direction.
- the crystal lattice is used as a normal X-ray optical element, the part behind the crystal, that is, the portion of the zone plate that contacts the membrane, should be made of the material that generates the desired X-rays. Therefore, the material is as described in the zone plate.
- any optical element is preferably placed on the rotation mechanism.
