Abstract: Background

The failure compensation of superconducting cavity directly affects the stability of the proton beam, which is the focus of the study on accelerator-driven superconducting proton accelerator (C-ADS).

Purpose

This study aims to design and implement an experimental platform to explore the results of the failure compensation of superconducting cavity.

Methods

Based on experimental physics and industrial control system (EPICS) with embedded Linux system, programmable logic controller (PLC) was employed as the input/output controller (IOC) to communicate with the low level radio frequency (LLRF) of the cavity via the network of EPICS to obtain experimental results.

Results

Simulated failure data was quickly searched in IOC database, and the calculation of the time length of failure compensation at each stage was verified.

Conclusions

This experiment realized the rapid detection of failure of superconducting cavity and the automatic compensation operation of other cavities, which laid the foundation for practical application in future.
