Abstract :
A system is being tested for recovery of rf power by conversion to DC pulsed power. The system consists of a cyclotron autoresonance accelerator (CARA) and a single stage depressed collector. A 50 kV, 5 A electron beam is injected into CARA, and up to I MW of S-band rf power is absorbed by the beam with efficiency exceeding 95%. The beam then passes to a single stage depressed collector. RF to DC collection efficiencies of 73% are predicted but, due to collector breakdown above 125 kV, a maximum collector efficiency of only 41% has been observed to date
