摘要
Characterization of a very simple pulsed electron gun operating in the tens of keV range is presented. Electron emission is based on laser-produced plasma and electrostatic acceleration, generating a homogeneous beam of circular cross section. Electron bunches up to 0.5 nC in 20 ns pulses with 10 mA peak intensity were observed. A continuous energy spectrum was measured and analyzed.
