Description
Tracking detectors under preparation for the High Luminosity LHC, and for next-generation Higgs factories, hadron and muon colliders, will require components and mechanical structures providing unprecedented strength-to-mass ratios, thermal conductivity, and radiation tolerance. The CMS outer tracker incorporates such mechanical components to enable state-of-the-art functionality, including the central-section flat-barrel plank support structures and pixel-strip module spacers. At UC Davis, we have carried out a suite of complementary measurements of the thermal, mechanical, and radiation damage tolerance properties of materials such as carbon foam, carbon fiber, thermally conductive epoxies, and high-k materials such as AlCF and AlN. The findings are relevant for the CMS HL-LHC outer tracker and future tracking detectors.
