HIGH POWER TESTS OF CW INPUT COUPLERS FOR CERL INJECTOR CRYOMODULE

An injector cryomodule for the compact energyrecovery linac (cERL) requires six input couplers operating in CW mode. The input couplers were designed, fabricated and tested at a high power test system with a 300 kW CW klystron. The RF conditioning of the CW input couplers was successfully carried out at the test stand. The RF conditioning procedures and results are described.
