Abstract

Simulations are performed on the Stellant Systems, L-4953 crossed-field amplifier (CFA) in VSim. This is a high peak power (P_{out}{peak}approx 5 {mathrm{M}}mathrm{W}, P_{otau,t}{avg}approx 3.2text{kW}), moderate gain (G=11.2text{dB}), pulsed (t_{pulse}=1.8mu mathrm{s}, f_{pulse}=360 text{Hz}) L-band (f = 1.28 to 1.35 GHz), reentrant, backward wave, thermionic cathode CFA. Preliminary simulations predict P_{out}{peak} approx 7.5 text{MW} and text{Gain} = 11.7 dB at operation parameters in great agreement with specifications disclosed b y S tellant Systems. A new Child-Langmuir emission model recently introduced by TechX is tested on this crossed-field device, a nd predicts a n a node current of I_{a} = 120 mathrm{A}, which matches relatively well with the the specified anode current of 100 A.
