Title: High power high brightness electron beam generation in a pulse-line driven pseudospark discharge
Author: Destler, William; Segalov, Z.; Rodgers, J.; Ramaswamy, K.; Reiser, M.
Abstract: High brightness (~3×1010 A/m2rad2 ), high power density (~1010 W/cm2) electron beams have been generated by the mating of a hollow-cathode discharge device operating in the pseudospark regime to the output of a high power pulse line accelerator. Very small diameter (~1 mm) electron beams with currents in the range 500-1000 A and energies in the range 150-300 keV have been generated with measured effective emittances of about 85 mm-mrad. Such emittances are comparable to those achieved in conventional electron beam sources at current densities several orders of magnitude lower than those observed in these experiments
