Abstract
A plasma discharge is described which can produce a large‐area electron beam with energies up to 150 kV and current densities in excess of 1 A/cm2 for durations of the order of 20 μs. For voltages up to ∼120 kV, durations of 100 μs or longer are attainable without arcing in the discharge. The discharge has a smooth cathode and will operate with various fill gases at pressures of about 10 μ. The device is being developed as an electron gun for high‐pressure laser discharge stabilization.Keywords
