摘要

欧洲散裂源(ESS)是由13个欧洲国家合作建造的世界上最强大的中子源。该项目位于瑞典南部，正在接近建设阶段的尾声，第一批科学成果计划于2023年公布。本文概述了加速靶段(A2T)和泄油管线段(DmpL)中伽马阻滞剂(GBs)的机械设计。在波束线中存在的gb应该限制激活钨靶和波束转储发出的伽马辐射，以允许工作人员安全进入机器。所提出的设计允许有效的操作和相同的关闭时间独立于真空状态。

Mechanical design of the gamma blockers for the high-energy beam transport region of the European Spallation Source

Abstract The European Spallation Source (ESS) is a collaboration of 13 European countries to build the world’s most powerful neutron source for research. The project, situated in the south of Sweden, is approaching the end of the construction phase, and the first scientific results are planned for 2023. This paper gives an overview of mechanical design of the gamma blockers (GBs) in the accelerator to target (A2T) and dump line (DmpL) sections. The presence of GBs in the beam line should limit the gamma radiation emitted from the activated tungsten target and beam dump to allow the safe access of the staff to the machine. The presented design allows for efficient operation and the same shutting time independently of the vacuum status.
