超纯探测器组装线
An assembly line for the construction of ultra-pure detectors
摘要:
CUORE探测器的19个塔是由铜和PTFE加上二氧化碲晶体制成的超无线电纯组件组装而成,总共超过10,000件。必须使用专用装配线来处理和装配这些部件,以最大限度地降低在其构造期间和在安装到低温恒温器内之前的储存期间由外部介质引起的再污染风险。本文提出并为CUORE开发的装配策略和工具设计提供了解决方案,可扩展到对污染有严格要求的类似尺寸探测器的构建。
英文摘要:
The 19 towers constituting the CUORE detector are an assembly of ultra-radio-pure components made of copper and PTFE plus tellurium dioxide crystals for a total of more than 10,000 pieces. A dedicated assembly line is mandatory to handle and assembly those parts minimizing the risk of recontaminations induced by external agents both during their construction and their storage prior to installation inside the cryostat. The assembly strategy and the tools design, proposed in this paper and developed for CUORE, offer solutions that can be extended to the construction of similar-size detector with strict requirements on contamination.
