Description
The Dalian Advanced Light Source (DALS), proposed by the Dalian Institute of Chemical Physics (DICP), Chinese Academy of Science, Dalian, China, is a new Free Electron Laser (FEL) project based on superconducting radio frequency (SRF) cavity technology. Testing the Q0 performance of the cavity and measuring the static and dynamic cryogenic heat loads of the cryomodule (CM) are an essential qualification work before the CMs are installed in the accelerator tunnel. To support the performance test, a dedicated cryomodule test bench (CMTB) is being constructed at DICP. In this paper, the conventional heat load measurement methods and instruments used in CMs test are summarized. To improve heat load test accuracy and eliminate errors introduced by the feed box, feedcaps and endcap in the CMTB, a specified test adapter vacuum box is designed and conducted to connect the feed cap and end cap directly without the CM in-between. The first cool down status of the test bench and preliminary test result using the test adapter vacuum box is reported in this paper.
