COMPACT SELF-RESONANT X-RAY SOURCE

摘要

The present invention discloses an X-ray source which uses a rectangular cavity resonator, which is excited with a microwave TE 10p mode. The present invention also can be used as a source of cyclotron radiation, using the cylindrical cavity, but carrying out some structural changes thereof to achieve this purpose. This system allows significantly increasing the energy of the electron beam by compensating the diamagnetic force by an axially symmetric electrostatic field. The electrostatic field is generated longitudinally by ring-type electrodes placed inside the cavity, preferably in the node planes of the TE11p electric field. The electrodes should be made transparent to the microwave field, such as graphite.
