Abstract :
The 352-MHz high-power system for the Advanced Photon Source (APS) storage ring and booster synchrotron has been configured to allow two to four klystrons to power the storage ring and one klystron to power the booster. A quadrature hybrid combines two klystron outputs with two 45° phase shifters at each output of the hybrid for proper phasing at the storage ring cavities for the selected mode. The phase shifters in the hybrid outputs and three waveguide switches are used to choose an operation mode in any one of twelve possible configurations using three to five klystrons to power the storage ring and booster. The system can be configured to use one klystron as the power source of a test station
