17 Discussion - Magnetron life - Magnetron life in oven use: 5,000 hours in WPT use :? (1) filament temperature high (2000K) (filament-on operation) low (1700K) (filament-off operation) (2) operation ON/OFF ON: some minutes many ON/OFF repetitions thermal strain of the cathode ON: at all times of the year few ON/OFF repetitions (3) Output load mismatched (food) matched (antenna) Probability of magnetron life in MPT use: 100,000hours (10years) (Life test will be necessary.) 17
18 1. Magnetron Noise Reduction Magnetron internal feedback mechanism [Brown, Space Power, 1988] automatically sets the temperature of the cathode for quiet tube operation. This temperature turns out to be the lowest temperature The internal control of the cathode temperature works best when the external source of heating, the filament, is turned off and the control loop regulates the amount of electron back-bombardment to keep the filament at the desired temperature. Magnetron noise reduction by filament-off operation 18
