Abstract In order to safely absorb charged particle beams prepared for various experimental facilities at the European Organization for Nuclear Research (CERN) an external dump is installed at the end of the Proton Synchrotron (PS) transfer line. This dump currently consists of stacked cast iron blocks surrounded by concrete shielding. This paper analyzes the thermal performance of the PS external dump under today’s most critical beam operational scenarios. Thermal analysis using preliminary material models will be correlated with in-site thermal measurements on the open face of the dump. From this analysis we conclude on the thermal and structural consequences of further operation of the dump under current and future beam-operation scenarios in which beam intensities are expected to increase by a factor of three. Finally we analyze a new design proposal with active cooling for the consolidation of the PS external dump.

CERN 质子同步加速器多用途外部转储装置的热验证、结构影响和重新设计建议

摘要 为了安全地吸收为欧洲核研究组织 (CERN) 的各种实验设施准备的带电粒子束,在质子同步加速器 (PS) 传输线的末端安装了一个外部转储器。这个垃圾场目前由堆叠的铸铁块组成,周围是混凝土屏蔽。本文分析了当今最关键的梁操作场景下 PS 外部转储的热性能。使用初步材料模型的热分析将与垃圾场开放面上的现场热测量相关联。从这一分析中,我们得出了在当前和未来光束强度预计增加三​​倍的情况下,垃圾场进一步运行的热和结构后果的结论。
