Development of a Durable, Large Area Cathode for Repetitive, Uniform Electron Beam Generation.

摘要

Electra is a large-aperture, krypton-fluoride laser under development for inertial fusion energy research. The laser will require dual 500 kV, 36 A/sq cm, uniform electron beams operating at 5 Hz. Experimental studies have been performed to develop an approx. 3000 sq cm cathode capable of generating a 110 kA, 100 ns flat top beam pulse with minimal current density variation.
