Paper Abstract

Work begun in 1986 is continuing on the reflex-diode oscillator mounted on one of the Aurora 10-MV 22- ci pulsers. The most recent work extracted microwaves radially into six rectangular WR-975 waveguides at the virtual cathode and into two additional arms a few meters downstream. Two of the waveguides were open-ended and radiated into an anechoic chamber. Diagnostics for radially extracted microwave energy included directional couplers card calorimeters and free-field sensors. The peak output is ''-50 3 per arm for the frequencies below 1. 0 (3Hz. Parameter variations have included the anode/cathode spacing and the positioning of a second anode foil. Dosimetry and electric field measurements were made to study beani dynamics in the drift region. Thus far the measurements suggest that our virtual cathode is weak. 1.
