X-RAY SOURCE Russian patent published in 2017 - IPC H01J35/00 

FIELD: physics.

SUBSTANCE: in the claimed device, the massive anode contains a plurality of through channels focusing the X-ray radiation in a predetermined manner by combining their directions, and also because the channel walls may contain the target material not along the entire length. The source window adjoins the surface of the anode fixed on the body and does not experience dangerous loads even with a large window area, which reduces the requirements for window material, which can be made thin enough to transmit X-rays. The anode of the proposed source, due to the substantial thickness, is able to divert large heat fluxes to the ends provided with heat sink means.

EFFECT: increased power of the X-ray source.
