Abstract :
We present a progress report on a program to develop a high-power X-band magnicon amplifier for linear accelerator applications. The goal of the program is to generate 50 MW at 11.4 GHz, using a 200 A, 500 keV electron beam produced by a cold-cathode diode on the NRL Long-Pulse Accelerator Facility. The initial experiment, designed to study the gain from the first (driven) deflection cavity to a second (passive) deflection cavity, has been completed. A gain of ~15 dB has been observed in the preferred circular polarization, at a frequency shift of approximately -0.18%, in good agreement with theory and simulation. In addition, a design study for a complete magnicon circuit is under way
