Development of a CO2 Cooling System for the CBM Silicon Tracking System — •Jorge Sanchez Rosado for the CBM collaboration — GSI Helmholtzzentrum, Darmstadt
The Silicon Tracking System (STS) is the central detector system of the Compressed Baryonic Matter experiment (CBM) at FAIR. Its 2,5 million channel read-out electronics will dissipate ∼40 kW in a confined volume of 2 m3.
A two phase (evaporative) CO2 cooling system is taken as the first choice to extract the dissipated heat fulfilling the requirements such as reduction of mass budget and the use of smaller diameter for cooling pipes. The 2-Phase Accumulator Controlled Loop (2PACL) concept conceived at NIKHEF is the ideal method due to its stability and the only need of passive components inside the detector volume.
A 1 kW prototype plant is shown which is being assembled presently at GSI and will go into operation in summer 2014.
