Description
The Dalian Advanced Light Source (DALS) test facility has completed the com-missioning of the cold box in June 2024, and the first cooldown of the distribu-tion system began in September of that year. The whole cryogenic system re-quires helium inventory of 1.4 tons. For a more rational use of this helium, the helium distribution and the total inventory in the system are monitored, and a tool for monitoring the helium inventory is developed. With this tool, it is possible to understand the helium inventory changes intuitively and take effective measures to prevent the helium loss. In this paper, we analyze the changes in the helium in-ventory of the system after several cooldowns, and propose specific measures to reduce the helium loss.
