This paper presents a progress report on a program to develop a high power second harmonic magnicon amplifier at 11.4 GHz for linear accelerator applications. The experiments are being carried out on the single shot NRL Long-Pulse Accelerator facility using plasma cathode to create the electron beam. Typical beam parameters are 500-700 kV, 200-300 A, 5.5 mm diameter, with a 300 nsec voltage flattop. In preliminary experiments, a low power saturation effect was observed in the deflection cavities, apparently due to plasma formation caused by the diode X-ray flux and by inadequate vacuum conditions. Recent experiments have shown that it is possible to {open_quotes}burn through{close_quotes} this low power saturation effect, and achieve high fields in the deflection cavities in narrow gain spikes, combined with moderate power level emission from the output cavity.
