The program has the objective to design, develop, construct, and evaluate a high power S-band reentrant stream, crossed-field amplifier utilizing automatic self-modulation by RF drive power. The report covers the design considerations and cold test evaluation of the slow wave anode circuit, anode and cathode cooling techniques, and general construction of the proposed amplifier. Background information is given presenting the principles of operation of a reentrant stream crossed-field amplifier using a dc voltage between the cathode and the anode and a dc biased turn-off electrode to achieve automatic self-modulation by RF drive power. The results of one experiment intended to complete a series of experimental investigations of bias electrode geometries performed on another program are given. No significant additional improvement was obtained, but the experiment did confirm the present understanding of bias electrode operation. Author
