Summary of evaporative cooling system for the SSC silicon tracker

摘要

An evaporative cooling system has been developed for the Superconducting Super collider (SSC) Solenoidal Detector Collaboration (SDC) and the Gamma, Electron and Muon Detector (GEM) silicon tracker electronics. The system operated on the principles of the heat pipe; specifically, evaporation at near vapor-liquid equilibrium without the presence of noncondensible gases, and with a capillary media used to distribute the working fluid. The system used butane as a working fluid for operation at O(degrees)C and 1 atm. pressure. This paper summarizes the evolution of the system design, emphasizing key developments that may be useful for further work. Results of the system performance as of the close-of-effort are presented. A brief summary of results of experiments using a pumped single-phase cooling system are also presented.
