Description
Taiwan Photon Source (TPS) is a 3 GeV third-generation light source operating at a storage current of 500 mA. It currently operates with two RF stations, each capable of providing 300 kW of RF power. In the original design, each RF station employed a 500 MHz klystron-type RF transmitter. In August 2023, we switched one of the klystron-type RF transmitters to a 500 MHz home-made solid-state power amplifier, and it has been operating stably during user beam time. To accommodate the construction of more beamlines in the future, we plan to increase the total output power of each RF station to 375 kW through power combination. This report describes the operational status, including that of the SSPA, and the future plans for power combination along with the results of existing power combining tests.
