Abstract :
A high power gyro-TWT operating in the low-loss TE01 mode is being tested at UCD that is driven by a 100 kV, 5 A, ν⊥/νz=1.0 MIG electron beam with Δνz/νz=5%. The amplifier is predicted by a large-signal simulation code to generate 140 kW at 94 GHz with 28% efficiency, 50 dB saturated gain and 5% bandwidth.
