Description
Future silicon trackers target a drastic material budget reduction while requiring highly effective cooling and mechanical stability. Through standard micro-fabrication processes, it is possible to produce ultra-thin thermal management devices tailored to specific applications and largely overcoming the performance of traditional cooling approaches. The NA62 experiment has recently adopted a cooling solution based on a 130 micron-thick silicon micro-channel plate for its GTK detector and proposals are presently being considered for the upgrade of the ALICE ITS and of the LHCb Velo (the latter detailed in a separate paper). Silicon micro-fabrication techniques also provide powerful means for improved engineering of tracking detectors: realistic silicon mock-ups of chips and sensors permit to anticipate detailed module integration studies: thermal management, planarity issues, mechanical stability, wire bonding and servicing, among others. In perspective, the adoption of MEMS-based (Micro-Electro-Mechanical Systems) solutions for local sensing and actuation might also allow for a new generation of “smart” detectors with improved performance and reduced mass.
