200 KV Linear Beam Switch Tube Development

Abstract

This report covers the design, fabrication and processing of a linear beam pentode switch tube developed by Varian for RADC. Earlier models were developed by Varian for RADC. Earlier models were developed for Varian under Air Force sponsorship. Design goals were 200 kV video output at 180A load current and 0.04 (0.02 min) duty cycle at pulse lengths up to 100 usec. Important features are the nonintercepting grid convergent electron beam passing through the anode intermediate electrode and voltage depressible collector probe system. The intermediate electrode is positioned between cathode and anode. Primary function of the electrode is to limit the dc voltage in the gun region between electrodes, to about 125 kVdc. No beam tests were done by the contractor. Report includes recommended values for tube operating parameters.
