Abstract
Operation of the Naval Research Laboratory K-u-band ubitron has succes
sfully demonstrated a high power/efficiency and broad bandwidth. This
device employs a helical wiggler/axial guide field configuration. Perf
ormance levels achieved at 16.6 GHz can be summarized as a peak power
of 4.2 MW for an efficiency of 17.5% and a gain of 29 dB, and an insta
ntaneous bandwidth of 22%. Substantial beam loss was observed. The spe
cific loss rate was correlated with output power, and reached a level
of 50% beam loss at the 4.2 MW level. Nonlinear simulations of the exp
eriment are in good agreement with these observations.
