Funding: Work supported by Shanghai Municipal Science and Technology Major Project (Grant No. 2017SHZDZX02)
Shanghai HIgh repetition rate XFEL aNd Extreme light facility (SHINE) is under construction. The 8 GeV superconducting Linac consists of seventy-five 1.3 GHz and two 3.9 GHz cryomodules. A cryomodule assembling and test workshop is established. Multiple platforms have been built for cryomodule and superconducting cavity test, including two vertical test platforms, two horizontal test platform, one multiple test platform and one liquid helium visualization platform. The local control systems are all based on Yokogawa PLC, which monitor and control the process variables such as temperature, pressure, liquid level and power of the heater. PID and other algorithms are used to keep liquid level and power balance. EPICS is adopt to integrate these platforms’along with vacuum devices, solid state amplifiers, LLRF and RF measurement system, etc. The details of the control system design, development and commissioning will be reported in this paper.
