OPERATION OF THE HIGH POWER RF SYSTEM FOR PEFP RFQ

A high power RF system for PEFP RFQ has been developed and operated. The required peak power is 535kW, and pulse width, repetition rate for initial operation are 100µs, 10Hz respectively. All of the RF components including RF window, input coupler, klystron power supply and cooling system have the capacity of operating at 535kW average power level. Therefore RF duty can be increased for higher average power operation. The TH2089F klystron was operated in pulse mode by modulating the input RF power. The RF power from the klystron was divided into two legs and delivered to RFQ. In this paper, the system description and operation results are presented.
