CO2 cooling for particle physics detector.

Author(s) : COLIJN A. P., VERLAAT B.

Summary

A good cooling system is of crucial importance for particle and radiation detector systems that are used in elementary particle physics. In addition to the "normal" design considerations for a cooling system, the systems used in particle detectors are subject to additional unusual constraints. At the Dutch institute for sub-atomic physics - Nikhef - the authors have developed a technique for cooling particle physics detectors with CO2 (2-phase accumulator controlled loop or 2PACL). The LHCb experiment at CERN uses this technique successfully to cool a silicon strip detector with a power of 2 kW. The coolant temperature can be set between 8 and -35°C while the temperature fluctuations are well below 0.1°C. The authors give an overview of the requirements for cooling (silicon) detectors in particle physics and explain the 2PACL technique they have developed for CO2 cooling and they will show the results obtained with the LHCb experiment at CERN. In addition, they give preliminary results on the ongoing research on heat transfer and gear pump performance for the development of CO2 cooling systems for the next generation detectors.
