Abstract

New calculations confirm the ability of a random apriori initial-phase proton beam to drive a simple, single stage microwave cavity maser or transit-time oscillator (TTO) to saturation conversion efficiencies of = 11%. The required initial TE011 mode field can be provided from beam ramp-up bandwidth or excitation to a low level from an external source. A saturation field of 45 tesla, output power of .2TW (power density 2.2x10¹³ W cm 2) is calculated using an electron insulation field of 10 tesla and a 3 Mev, 400 Ka/cm² beam. (Addition of a "catcher" cavity can increase overall efficiency to = 15%.) Results are compared to those for an electron beam of the same energy and geometry, and it is shown that proton beams can potentially provide a three order of magnitude increase in over-all microwave power production density over that obtainable from electron beam TTO's.
