Design of the 150 KW, 46-62 MHz Power Amplifier for the TRIUMF Kaon Factory Booster Ring

摘要

The RF amplifiers for the Kaon Factory booster ring must be capable of reactively compensating (detuning) for the injected/extracted beam load as well as providing the beam power and the cavity losses. In order to insure the stability of the RF system under heavy transient and steady state beam loading conditions, it is necessary to equip the power amplifiers with fast RF feedback with sufficient gain and bandwidth to reduce the apparent Q of the RF amplifier system as seen by the beam and the other feedback loops. The maximum gain and bandwidth of such a feedback loop is limited by the propagation delay a 2.4 kW two stage solid state driver will be used to drive the cathode of the Eimac Y567B tetrode to give an overall propagation delay less than 30 nS. The design features of the RF amplifier to meet the above conditions will be described and test results reported. 7 refs., 7 figs. (ERA citation 13:047252)
