Abstract :
National Synchrotron Radiation Research Center (NSRRC) is planning to install two 500 MHz superconducting radio frequency (SRF) cavities and six superconducting magnet (SM) modules. For the cryogenic requirements, we are presently constructing a helium cryogenic system. The cryostat properties of the SRF cavities and the SM modules are so different that in our design the cryogenic system has two cryogenic plants (465 W or 110 liters per hour @ 4.5 K for every plant), one is for the SRF cavities and the other is for the SM modules. The two plants are independent in normal operation. However, when the cryogenic plant for the SRF cavities shuts down, the other one can be transferred to supply the SRF cavities, and we design a distribution valve box to carry out the transformation.
