FPGA based cavity simulator for TESLA Test Facility

This paper presents a FPGA based DSP system for realtime simulation of superconducting accelerator’s cavity. The super- conducting linacs require sophisticated control systems for maintaining the constant amplitude and phase of accelerating field in the accelerator’s cavities. The debugging of these systems on real hardware can be both difficult and dangerous.To allow testing of the real LLRF systems in the real time and with different cavity parameters, the FPGA based system has been developed.
