Abstract: An X-ray source with optical indication of radiation, which can be used in various measuring devices for parameters control and visualization of structure of industrial and biological objects, is proposed. The source comprises a vacuum housing, an anode irradiated by electrons and generating the divergent flux of radiation, an exit window for X-ray radiation, means for optical indication of X-ray radiation beam including a source of optical radiation and an optical mirror. The anode is made composite in the form of a thin film and a radiolucent substrate luminescent in the optical range. The anode structure is an exit window of the source, and behind it the coaxially arranged means of collimation and focusing of X-ray and optical radiation and means of optical visualization of X-ray focus are mounted. The proposed device significantly increases the accuracy and informativity of optical indication of X-ray radiation parameters.

Abstract: An object of the invention is to provide an X-ray generator having a simple configuration where heat generated in the irradiation window can be prevented from conducting to a desired portion in accordance with the purpose of use, the method of use or the structure of the X-ray tube. In an X-ray generator for releasing X-rays generated by irradiating a target placed in a vacuumed atmosphere within an X-ray tube with an electron beam from an electron source through an irradiation window of the X-ray tube, the irradiation window has thermal anisotropy where the thermal conductivity is different between the direction in which the irradiation window spreads and the direction of the thickness of the irradiation window, and therefore, the thermal conductivity in the direction in which the heat from the irradiation window is desired not to conduct is made relatively smaller.
