Abstract
The present disclosure provides a device and an equipment for radiation ray generation. The device may include: a radiation target assembly configured to generate radiation rays under irradiation of an electron beam with a predetermined energy; and a heat dissipation assembly arranged on a back surface of the radiation target assembly, wherein a range of a thickness of the target assembly may be determined based on a peak of energy deposition of a target material of the radiation target assembly under the irradiation of the electron beam with the predetermined energy.
