Description
Ultra-thin liquid micro-fluidic silicon devices have been recently selected for the active thermal management of the GigaTracker detector in the NA62 experiment at CERN. Following this first successful application, further studies have been launched on two-phase flow devices for the upgrades of the ALICE Inner Tracker System (room temperature and low pressure) and LHCb Vertex Locator (low temperature and high pressure) detectors. Recent developments at CERN on this subject will be discussed, including thermal performance, material budget impact, structural reliability and hydraulic connector issues.
In the frame of a collaboration agreement with CSEM (Centre Suisse d'Electronique et Microelectronique), studies are also on-going towards the fabrication of a demonstrator gathering micro-channels for cooling and fine-pitch TSV for interconnectivity in the same device. The status of this R&D aiming to an active silicon interposer will be presented.
