摘要：
The authors describe a technology for fabrication of explosive-emission cathodes based on carbon-fiber plastic of practically any shape or size. The current rise of electron beams from cathodes 2 cm in diameter is studied experimentally with diode voltages of 10 kV and 150-250 kV. It is shown that the cathode-plasma ignition voltage is 2 kV for an interelectrode gap of 5 mm and a residual-gas pressure of 5&middot10-5 torr. A carbon-fiber cathode produced by this technology provides a more-stable rise of electron-beam current (without oscillations) than other cathodes.
