Effect of a peaking circuit on the power rise time in the magnetron

The operation, in terms of power rise time, of a magnetron with and without a peaking circuit was examined theoretically. It was found that without the peaking capacitor, the current struggles slowly to its peak value and the magnetron power rises hesitantly. With the peaking capacitor, the current and voltage struggles up to approx. I/sub 0/ and .8 V/sub 0/ whereupon the magnetron turns on and the voltage across it rises very rapidly from its threshold value (.8 V/sub 0/) to its peak value (V/sub 0/). Further considerations lead to the inclusion of a resistance R/sub p/ in series with C/sub p/ to damp large voltage oscillations which may affect the performance of the magnetron. (LCL)
