Description
A 2K cryogenic system was constructed for DC-SRF injector and 2x9-cell cryomodule of the Peking University Free Electron Laser (PKU-FEL) facility. A stability of the helium pressure better than ±0.1 mbar and total refrigeration capacity of 65 W at 2K temperature has been reached with stable operation. A vertical test system for superconducting cavities was set up based on the 2K cryogenic system. A total cooling capacity of 200 W is got with the upgrade of the 2K pumping system. Vertical tests of superconducting cavities have been carried out successfully.
