  • Abstract
    The authors have developed 60 MW, 60% efficient, 35 Joule/pulse secondary emission magnetron at S-band. They report on experimental results from this moderate-voltage (120 kV), repetitively pulsed (10 Hz), injection-locked (14-15 dB gain) magnetron. Limits imposed by high-voltage breakdown, RF breakdown, and thermal loading are discussed. By increasing the voltage, the drive power, and the magnetron length and by using a tungsten alloy anode, 120 MW should be achievable for approximately 4- mu s pulses at 130 kV with the pulse length limited by transient heating of the anode.<>
