PURPOSE:To make it easy to adjust the operating frequency range by changing the length of inserted portion of a plunger provided in the external cavity resonator. CONSTITUTION:An external cavity resonator 2 is adjusted by a coupling adjust screw 12 so as to get the maximum coupling with an internal cavity resonator, and the electromagnetic wave energy is taken out from the external cavity resnoator 2 through a window hole 14 to the external load circuit. And, by changing and adjusting the electric capacity of the external cavity resonator 2 by use of a tuning rod 11, the frequency tuning can be done in the whole operating frequency range. Furthermore, the cavity configuration can be changed into various modes by providing a plunger 13 in a part of the external cavity resonator 2, and therefore a klystron with a different operating frequency range can be easily obtained. |
