The new ALS Main Ring 500MHz RF system will require significant modification of the existing HV power supply in which classical ignitron based crow-bar system will be replaced with house made solid state disconnect switch which is undergoing final high power test. The principle of the operation and the status of the testing will be presented.

BNL 704MHz SRF gun for ERL uses two high power fundamental power couplers (FPCs) to deliever 1MW CW RF power to gun cavity. Prior to install the FPCs to the cavity, we used the 1MW klystron to condition the two couplers. This paper will address design of the high power couplers, conditioning test of the FPCs. Multipacting simulation using Track3P and comparison with conditioning will be...

The APS 352MHz radio frequency test stand (RFTS) was constructed in 2002 primarily to test and condition storage ring and booster rf cavity components. Since the rf test stand’s inception, modifications have been made to increase the RFTS’s testing capabilities. These modifications include: the installation of a solid state switch / mod-anode regulator, a high-voltage switch tank, access to...

We have developed a cavity specifically used for the coupler conditioning. For the booster synchrotron, 5-cell cavities are used and maximum 300-kW RF power must be fed through the couplers, whereas for the storage ring single cell cavities are used and the power fed through the coupler is 150 kW at maximum. Each coupler should be conditioned before the installation to the actual machine. We...
