Abstract : Previous theoretical and experimental studies showed that microwave power may be generated from the electron beam-plasma interaction. T is analysis is concerned with achieving conditions in the plasma which allows microwave power generation on an electron beam traversing the plasma at frequencies above 300 kmc. Theoretical studies show the dependence of power gain on the length and the percent ionization of the plasma. A cesium plasma has been produced in a diode discharge with a density greater than 5 x 10 to the 13th power per cc (electron plasma frequency higher than 63 kmc) and an ionization of 25%. A novel approach to the problem of coupling microwave power to the plasma has been investigated theoretically. (Author)
