Abstract :
A 60-MW, 60% efficient, 35 J/pulse secondary emission magnetron at S-band has been developed. The authors report on experimental results from this moderate voltage (120-kV), repetitively pulsed (10-Hz), injection locked (14-15-dB-gain) magnetron. Results from particle-in-cell code computer simulations are presented which compare very well with the experiment when space-charge-limited emissions is assumed. 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.<>
