ATLAS experiment
02.06.2014 Lukasz Zwalinski ATLAS IBL CO2 cooling 2
Main system elements:• 2 independent, redundant cooling plant cores • 2 independent, redundant two stage chillers• 1 common accumulator with redundant control • Common interconnection piping for
maintenance operations including vacuum pump
• Integrated internal by pass and small evaporator for stand-by operation
Designed cooling power at -400C = 3kW
