Abstract
The emission characteristics of planar diodes for high-current nonosecond accelerators have been studied for two types of cathodes: plane and multiple-emitter. Curves are given of the pulsed emission current as a function of the electrode separation in the diode. The relatively high amplitude and the faster current risetime in a multiple-emitter cathode are attributed to the faster formation of the plasma emission surface; in turn this is due to field amplification at macroscopic emitters.
