Progress on the UoS PL-BWO Experiment

The University of Strathclyde (UoS), UK, is currently developing a novel Phase-Locked X-band Backward Wave Oscillator (PL-BWO), operating at a low confining-field of ~0.3T, with the aim of implementation as the microwave source(s) in a phase-synchronous array. Operating at a central frequency of ~9.6GHz, the BWO was predicted to generate 120MW, 1ns, pulses when driven by a 4ns, 210keV, 1.5kA RADAN 303B pulsed modulator [1-2].
