Rugged magnetrons of sophisticated characteristics

Design considerations are described, which have led to the development of a range of low power pulsed magnetrons at S, X, and J bands with peak powers in the range 0.15 to 35 kW, which display some or all of a number of performance characteristics. These include reliability in operation under shock and vibration, rapid switch on even after long storages, low missing pulse rate, rapid rise and fall of rf power, low jitter rate, operation at low ambient pressure and over wide temperature range, low temperature coefficient of frequency. Current work on further understanding the parameters limited performance is described.
