FPGA based real time RF cavity simulator for superconducting RF cavity

RF cavity is one of the most important component in an accelerator, it is used for producing appropriate electromagnetic fields to accelerate the charged particles. The response of RF cavity to an input RF signal depends on the various operating conditions. Actual operating conditions of RF cavity are difficult to create in lab and also RF cavity is not easily available which limits the study and testing of RF systems that involve RF cavity. This calls for the requirement of a real time hardware model of the RF cavity which can be integrated with other RF systems for their testing in lab. This limitation is even more severe for superconducting RF cavities which need to be operated with the required cryogenics. Thus a real time hardware model of the superconducting RF cavity has been realized on FPGA. Real time RF Cavity simulator can be used to study the response of RF cavity under various operating conditions and for testing and optimization of other RF sub-systems particularly the Low Level RF feedback control systems in lab
