Simulation for compensation of superconducting cavity in C-ADS injector

For the proton accelerators such as the China Accelerator Driven subcritical System (C-ADS), it is essential and difficult to achieve extremely high performance reliability requirement. Aiming at the failure problem of superconducting cavity in Injector-I in C-ADS, this paper gives simulation results based on Experimental Physics and Industrial Control System (EPICS) and PLC with embedded Linux system. The simulation completes the development of embedded system and quick seeking of data. The results not only verify the feasibility of such method, but also establish the foundation for further experiment. (authors)
