Abstract
A pulsed ferroelectric electron cathode with a current density of up t o 45 A cm(-2) based on (Pb, La)(Zr, Ti)O-3 ceramic is presented. The e xperimental set-up for the cathode triggering allowed us to achieve a perveance of more than 65 mu P and an energy spread in the generated e lectron beam as low as 100 eV (FWHM).
