The cathode was pulsed to 2.75 MV at fields of 185 kV/cm (15-cm AK gap) using REX (a 4-MV, 5-kA, 85-ns) pulsed-diode machine. The extracted current versus incident laser power (the quantum efficiency) was measured for KrF at 5x10{sup -5} and for ArF which was significantly higher at 1x10{sup -3}. Current densities of 100 A/cm{sup 2} and total currents of 2 kA have been achieved, the latter by increasing the cathode area in proportion to the laser power.
