The LHCb Vertex Detector (VELO) is currently being upgraded to a lightweight, capable pixel detector of 40 MHz. The thermal management of the system will be provided by evaporative CO2 circulating in micro channels. This solution has been selected because of the excellent thermal efficiency, the absence of thermal expansion, as well as the ability of CO2 and the contribution to the material...
Mu3e is an upcoming experiment at Paul Scherrer Institut in the search for the strongly suppressed decay of µ->eee. It will use an ultra-lightweight silicon pixel detector using thinned HV-CMOS MAPS chips. Untriggered, zero-suppressed, always-on operation is needed for observing random decays of muons at rest with a decay rate of 10^8-10^9 decays per second. More than 1 m2 of instrumented...
In a continuous effort to push the energy frontier, CERN’s Large Hadron Collider (LHC) will undergo a major upgrade which will extend its service life and boost the potential for new discoveries beyond 2025. Along with a ten-fold increase in the rate of collisions, the High Luminosity LHC (HL-LHC) is expected to reach unprecedented levels of radiation. In parallel, in the ATLAS experiment an...
For the CERN LHC Run 3, the ALICE experiment completely redesigned the Inner Tracking System, now consisting of seven cylindrical layers instrumented with 24120 Monolithic Active Pixel Sensors (MAPS), covering a total surface area of 10 m2. The readout and powering systems are composed of 192 identical Readout Units (RUs) and 142 Power Boards (PBs), respectively, and have complete control over...
The upgrade of the Large Hadron Collider for the High-Luminosity (HL-LHC) phase, will introduce extreme operating conditions for the CMS Inner Tracker, including hit rates of 3.2 GHz/cm2 and a trigger rate of 750 kHz. The radiation levels will be reaching the unprecedented levels of 1.25 Grad of Total Ionizing Dose (TID) and a hadron fluence of 2.3×10^16 neq cm−2 for 10 years of operation. In...
Optical data links have become ubiquitous in modern High Energy Physics experiments. Since their first large scale use in LHC detectors, they have proven to be extremely robust, reliable and resistant to radiation and magnetic fields. Based on this positive experience, optical links operating at higher and higher data rates have been qualified for use in a broad range of detectors worldwide....
