ABSTRACT:
There are provided an anode target which generates X-rays due to electrons e being incident, an emitter source which emits electrons e to be incident into the anode target, a ring-shaped recoil electron capturing structure which surrounds an orbit of electrons e heading from the emitter source toward the anode target, and captures electrons e emitted from the emitter source and recoiled on the anode target, and a vacuum envelop which keeps at least a periphery of the anode target, the emitter source, and the recoil electron capturing structure at a predetermined degree of vacuum, and the recoil electron capturing structure has a first member formed from strengthened copper which is exposed to the inside of the recoil electron capturing structure, and a second member formed from copper which is disposed at the outside in the radial direction of the first member.
