Cooling: Experience from AtlAS & CMS

Proceedings of Science 95 (2009)

Abstract:

The cooling system of a large scale silicon detector system is critical for the long term operation of detectors in the harsh radiation environment of the LHC. The ATLAS and CMS experiments have developed and commissioned their large and complex distributed systems over the last few years. The systems are now complete and are in operation. In this publication I will describe the ATLAS and CMS systems and summarise some of the experience gained in the development and operation of these systems.

Abstract:

This paper describes the evaporative system used to cool the silicon detector structures of the inner detector sub-detectors of the ATLAS experiment at the CERN Large Hadron Collider. The motivation for an evaporative system, its design and construction are discussed. In detail the particular requirements of the ATLAS inner detector, technical choices and the qualification and manufacture of final components are addressed. Finally results of initial operational tests are reported. Although the entire system described, the paper focuses on the on-detector aspects. Details of the evaporative cooling plant will be discussed elsewhere. © 2008 IOP Publishing Ltd and SISSA.
