The MIP Timing Detector (MTD) is introduced in the CMS experiment to measure the production time of MIPs. Power Conversion Cards (PCCs) regulate low-voltages in the MTD barrel region. They host three radiation and magnetic field tolerant DC-DC converters. The height of the PCC is limited to 7 mm. This necessitated the development of custom inductors and shields. Additionally, the CMS...
The upgraded CMS tracker for HL-LHC is going to require more than 200 kW power. Two different powering strategies are being adopted for the Inner Tracker and the Outer Tracker. The talk describes the two powering schemes and discusses the intrinsic constrains. Specifications for the powering units and for the cables of the two systems are outlined in combination to preliminary results with prototypes
The high luminosity upgrade for the LHC at CERN requires a complete overhaul of the current inner detectors of ATLAS and CMS. A serial powering scheme has been chosen to cope with the constraints of the new pixel detectors. A prototype stave consisting of up to 8 quad modules, based on the new readout chips developed by the RD53 collaboration in 65 nm CMOS technology, RD53A and ITkPixV1, has...
