Embodiment Construction

[0067] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. figure 1 It is a schematic structural diagram of an X-ray generator using hemimorphic crystals according to an embodiment of the present invention. like figure 1 As shown, the X-ray generator of the present invention has a container 1 that maintains an internal low-pressure environment (3-6 Pa). In this embodiment, the container 1 is formed of an X-ray-impermeable material (for example, metal) and has a cylindrical shape with both ends open and closed. On a wall of the container 1 , for example a side wall, there is at least one x-ray transparent window 2 formed of, for example, Be or an x-ray transparent plastic.

[0068] In addition, Peltier units 3 a and 3 b are airtightly joined to the upper wall and the bottom wall of the container 1 via a sealing member 4 such as an O-ring. In this embodiment, the Peltier units 3a, 3b not only function as heating / cool...

Abstract

A container (1) for maintaining an internal low-pressure environment; a hemimorphic crystal support device (3a, 3b) disposed inside the container; inside the container, it is supported by the hemimorphic crystal support device, leaving a distance from each other At least one pair of hemimorphic crystals (5a, 5b) that are arranged oppositely and the temperature raising and lowering device (3a, 3b; 6a, 6b~8a, 8b) that make the temperature of the above-mentioned hemimorphic crystals rise and fall, pass through the above-mentioned device, along with the above-mentioned The rise and fall of the temperature of the hemimorphic crystal, and the X-rays emitted from the above-mentioned container.

Description

technical field [0001] The present invention relates to an X-ray generator using hemimorphic crystals and an ozone generator using the same. Background technique [0002] Currently, an electron gun X-ray generating device is well known as an X-ray generating source. In the electron gun X-ray generator, almost all the electron energy injected into the target is converted into heat, and the conversion efficiency into X-rays is as low as 0.1%, so improving the conversion efficiency has been a very important issue until now. [0003] Therefore, an X-ray generating source using a hemimorphic crystal obtained by solving this problem has recently been attracting attention (see, for example, Non-Patent Document 1). Hemimorphic crystals have the following characteristics, also known as pyroelectric crystals. Repeated heating and cooling causes the temperature to rise and fall, resulting in spontaneous polarization changes inside the crystal, and the surface adsorption charge changes...
