An assembly line for the construction of ultra-pure detectors
  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.
