The TRIUMF e-linac high power system will be built in stages. For the first phase of installation to be completed by September 2014, the injector cryomodule (EINJ) will be fed by a 290 kW cw at a reduced power level and the accelerating cryomodule (EACA) will be powered by an identical 290 kW CW klystron. The second klystron and second high voltage power supply are also being procured from CPI and Ampegon respectively. The 290 kW cw 1.3 GHz klystron is a factory tuned multi-cavity, high efficiency, high gain, broadband, water cooled tube. The klystron has been tested at the factory. The maximum usable linear range of the rf output power of the klystron is 270 kW and is governed by the incremental gain of 0.5 dB/dB. The high voltage power supply system (KPS) for the klystron, based on a voltage controlled power module technology, consists of 65 kV beam power supply, focus supply, filament power supply and vacuum ion pump power supply. The klystron will be tested to full power on a dummy load by October 2013. At the same time, the KPS will be tested fully with all controls, interlocks, protections and integration of the klystron and a 300 kW high power circulator.
