X-RAY RADIATOR WITH A THERMIONIC PHOTOCATHODE |
摘要 |
An x-ray radiator has an anode that emits x-rays when struck by electrons, a cathode that thermionically emits electrons upon irradiation thereof by a laser beam, a voltage source for application of a high voltage between the anode and the cathode for acceleration of the emitted electrons towards the anode to form an electron beam. A surface of the cathode that can be irradiated by the laser beam is at least partially roughened and/or doped and/or is formed of an intermetallic compound or vitreous carbon.
