Název v původním jazyce

A Versatile Evaporative Cooling System Designed for Use in an Elementary Particle Detector

Popis výsledku v původním jazyce

We report on an evaporative cooling system developed for operation and qualification testing of silicon pixel and microstrip detectors for the inner tracking detector of the CERN ATLAS spectrometer. Silicon detector substrates must be continuously operated between 0&#186;C and -7&#186;C in the high radiation environment near the circulating beams at the LHC. This requirement imposes unusual constraints on the cooling system and has led to the choice of perfluoro-n-propane (C3F8) refrigerant, which combines good chemical stability under ionizing radiation with high dielectric strength and non-flammability. Since the silicon detectors must also be of extremely light construction to minimize undesirable physics background, coolant tubes are of thin (200ľm) wall aluminum while evaporative operation allows a very low circulating coolant mass-flow (1-2 g.s-1/100W to evacuate).
