The Minimum Ionizing Particle (MIP) Timing Detector (MTD) is introduced in the CMS experiment to measure the time of MIPs. The MTD consists of 432 Readout Units (RUs) in its barrel region (BTL), each powered by two Power Conversion Cards (PCC). PCCs host three radiation and magnetic field tolerant DC-DC converters. More than 1,000 PCCs will be produced to satisfy the assembly needs of BTL with...
Maintaining the required performance of the CMS electromagnetic calorimeter (ECAL) barrel at the High-Luminosity Large Hadron Collider (HL-LHC) requires the replacement of the entire on-detector electronics. 12240 new very front end (VFE) cards will amplify and digitize the signals of 62100 lead-tungstate crystals instrumented with avalanche photodiodes. The VFE cards host five channels of...
This study evaluates the lifetime and aging process of the aluminium electrolytic capacitors to be used in the new protection systems of the High Luminosity LHC superconducting magnets. The accelerated testing and analysis of several groups of capacitors aged for more than one year provided insights into their expected lifespan and aging process. The results obtained have practical...
The Low-Power Gigabit Transceiver (lpGBT) is a radiation-tolerant ASIC used in high-energy physics experiments for multipurpose high-speed bidirectional serial links. Almost 200,000 chips have been tested with a production test system capable of exercising the majority of the ASIC functionality to ensure its correct operation.
Furthermore, specific individual qualification tests were carried...
The CMS Tracker Phase-2 Upgrade requires the production of new sensor modules to cope with the requirements of the HL-LHC. The two main building blocks of the Outer Tracker are the Strip-Strip (2S) and Pixel-Strip (PS) modules. All-together 47520 hybrid circuits will be produced to construct 8000 2S and 5880 PS modules. The circuit designs for the mass production were fine tuned and the...
