Description
SHINE, the Shanghai HIgh repetitioN rate XFEL and Extreme light facility, a quasi-continuous wave hard X-ray free electron laser facility, is currently under construction. The SHINE cryogenic system is divided into three groups, the test facility cryogenic system, the accelerator cryogenic system and undulator cryogenic system. Among the three cryogenic system, the test facility cryogenic system is the first system to be designed, procured, installed and commissioned. It is designed to provide 1kW cooling power at 2K with mixed cycle using both cold compressor and warm process pumps. Up to now, the warm compressor system, cold box system integrated with cold compressor, process pumps system, and the distribution system have already been installed and are now under commissioning. Meanwhile, the accelerator cryoplant with a capacity of 12kW@2K in total has been procured and is now in the design phase. In this paper, the design specification, process analysis, system scope, conceptual layout, description of single compotes, and preliminary schedule of the cryogenic system for the SHINE test facility and accelerator system will be introduced.
