Cooling strategies and thermal analysis of a module of the NA60 silicon tracking telescope

This note reports on the thermal studies performed on the silicon tracking telescope used in the NA60 experiment during the runs with the proton beam. To ensure adequate operating conditions, it is of the uppermost importance that the heat dissipated by the electronics doesn't provoke unacceptable temperatures on the telescope sensors. Furthermore, to prevent damages in the circuits, condensation should, as well, be avoided. After a brief description of the modules, the issues related to the cooling strategy are addressed. The model for the study, made using a CFD (Computational Fluid Dynamics) code, is then presented and the results and conclusions of the simulations will follow.
