Remote Tuning of Magnetron Frequency in an RF Linac

A 6 MeV electron beam, RF Linac system was developed to operate at a frequency of 2856 MHz. The RF power source to the Linac is a magnetron. During operation of the Linac, loss of RF power changes frequency of both the Linac as well as magnetron. The magnetron RF output power frequency needs to be changed remotely to feed maximum power into the Linac. This paper presents theory and the developed system.
