Lightweight Thermal Management Strategies for the Silicon Detectors of CBM at FAIR

Lightweight thermal management is central to the design of the all-silicon Inner Tracker of the Compressed Baryonic Matter Experiment (CBM) at the Facility for Antiproton and Ion Research (FAIR). This experiment aims to study strongly interacting matter at neutron star core densities through fixed-target Au-Au collisions (\(\sqrt{s_{NN}} = 2.9 - 4.9\,\)GeV; up to 10\(^7\) beam-target interactions per second; polar angular acceptance of \(2.5^{\circ} \leq \Theta \leq 25^{\circ}\)). Studies with thermal demonstrators for both the pixel-based Micro Vertex Detector and the strip-based Silicon Tracking System have validated their thermal management strategies, preparing them for series production now and global commissioning in 2028.
