3. 14-Mar-13Work Package 13 - CO2 Cooling - Jorge Sánchez3 The requirements for the STS cooling are twofold: The innermost sensors with high radiation load have to be kept at or below -5 ⁰C Cooling based in gaseous, convective cooling of the (innermost) silicon sensors and other heat generating components, like power cables. Complete removal of the heat dissipated by the front-end electronics boards. This a prerequisite of the first requirement. System based in an evaporative CO 2 cooling of the front-end electronics, which is located in the FEE blocks. This kind of evaporative cooling based on CO 2, is also under consideration and thus under intense technical development for upgrades of the silicon trackers of LHC experiments. The total heat power dissipated by the STS components is estimated as: 212 FEE blocks at 200 W (10 FEBs with 20 W each), resulting in a power dissipation of 42.4 kW. The innermost sensors around the beam pipe with the highest radiation load will dissipate in operation around 6 mW on (2 x 3) cm 2 after the accumulation of a certain radiation dose.
