E-Gun Technology

Abstract

This program has two main objectives: the first is to develop broad area cathodes which can deliver current densities of 10-20 A/sq cm for several microseconds in duration and for pulse repetition rates of 25 Hz (near term) and up to 100 Hz (long term); the second objective is to develop techniques for foil cooling in the regime somewhat 100 W/sq cm. These techniques include foil materials, both singular and composite structures, active methods of heat removal and support structures which provide good heat conductivity, proper support for the thin foils and high e-beam transmission and efficiency.
