Abstract : This program was intended to show the feasibility of producing pulse and CW microwave power at S-band in the range of hundreds of average kilowatts. The program was divided into three major phases, a CW tubes development, a pulsed tube development, and the design and construction of high-power test equipment. The objectives of the CW development were to produce a minimum of 400 kilowatts power output at 3000 Mc. The objectives of the pulsed tube development are classified. The test equipment phase of the program consisted of the construction and installation of both tubes simultaneously and independently. A total capacity in excess of 3000 kilowatts was installed. Supplementary research work in the areas of cathode secondary emission studies, highpower microwave windows, and high dissipation cooling techniques was also conducted. During the earlier phases of the development existing low-power test equipment was used until parts of the high-power facility were completed. The CW portion of the installation was operational 22 months after the start of the program; the pulsed equipment was in full operation 18 months later. With the achievement of 425 kilowatts of power output in the final tube models of the CW program, substantially all of the program objectives had been accomplished. (Author)
