内容記述 | We study a disk cathode in the weakly relativistic region less than 100 kV by comparing the conventional tubular cathode. The disk cathode is an explosive electron emission cathode made of bare metal. The beam generated by the disk cathode has the more uniform distribution and has the higher current density compared with the tubular cathode with velvet. For the uniform emission, some surface roughness of 1 ����m order is required on the emission surface. Metals such as aluminum, copper and stainless steel are tested as the cathode. Up to now, the best result is obtained by a copper cathode. In view of application to the weakly relativistic oversized backward wave oscillator, the disk cathode is superior to the tubular cathode and is effective for the high-power operation. | |||||
