Development of solid state modulating anode power supply for 1 MW Klystron system

摘要

Bhabha Atomic Research Centre (BARC) Mumbai is developing Low Energy High Intensity Proton accelerator (LEHIPA) of energy 20 MeV, 30 mA. LEHIPA comprises of Radio Frequency Quadrupole (RFQ) accelerator (3 MeV), 10 MeV Drift Tube Linac (DTL) and 20 MeV Drift Tube Linac (DTL). As per the accelerator physics design, RFQ and DTLs require about 2.4 MW of total radio frequency (RF) power. Each accelerating cavity will be driven by a 1MW continuous wave (CW) klystron (TH2089F) amplifier at 352.21 MHz. LEHIPA will operate in both, pulsed and CW mode So, the RF system is being designed to operate in the both, CW and pulse mode.
