Microsecond Electron Beam Diode Closure Experiments
Abstract
Experiments have been conducted on the Michigan Electron Long Beam Accelerator (MELBA) to explore diode closure and voltage compensation during collapsing diode impedance. MELBA operates with parameters: Voltage = - 0.6 to -1.0 MV; Current < 60 kA; and Pulselengths exceeding 1 micro s. A reverse charged ringing circuit compensates the Marx generator output voltage to within +/- 7 % (+/- 10%) for pulselengths of 1 micro s (1.4 micro s) in a 127 ohm resistive load. Electron beam generation experiments have utilized two types of field emission cathodes: carbon brush and velvet cloth. Total electron beam pulselengths of 4 micro s have been achieved.
