LOW-LEVEL RF CONTROL SYSTEM FOR THE TAIWAN PHOTON SOURCE

The low-level RF (LLRF) control system is an essential component of the RF system for Taiwan Photon Source. The LLRF control system will perform various functions including control loops for the cavity gap voltage and the phase feedback, RF system interlock protection and the diagnostics for a machine trip. The LLRF system is manufactured in house using the most recent commercial RF chips. The LLRF system has an analogue architecture similar to that used in the 1.5-GeV Taiwan Light Source (TLS). An overview of the system architecture and its functionality is presented herein.
