Description
The design of a distributed pumping system using NEG (Non-Evaporable Getter) strips for the slender beam pipes of the Hefei Advanced Light Fa-cility (HALF) is presented. To achieve a high pumping speed and pumping capacity in a limited pumping space, a NEG strip with distributed pumping capacity was considered. A prototype of HALF vacuum cham-ber, which can be inserted into NEG strip and matched with magnet system, is designed. The activation tem-perature of NEG strip and the ultimate vacuum after activation are tested, and the results are in good agreement with those obtained from the simulation.
