The Mu2e calorimeter and read-out electronics are hosted inside the superconducting magnet cryostat and exposed to an intense flux of ionizing and non-ionizing particles. The performance of a number of components is compromised by radiation damage. This includes the scintillating crystals and silicon photomultipliers (SiPM) whose performance degrades proportionally to both dose and neutrons...
The RD53B chip for HL-LHC upgrades of ATLAS and CMS needs to provide reliable operation in a radiation hostile environment with inevitable Single Event Effects. To answer the challenge, substantial efforts are made to protect and evaluate the critical parts of digital logic with different TMR schemes and to characterize the on-chip CDR. Cross-section for each TMR scheme and its effective SEE...
To test the performance of the future pixel readout chip in the harsh High Luminosity LHC (HL-LHC) environment, an irradiation experiment has been setup with gaseous Kr-85 beta source with dose rate of about 7 rad/s. This setup was designed to emulate as closely as possible operation in the HL-LHC conditions of the ATLAS detector inner layer, including temperature, radiation, and continuous...
The MALTA family of depleted monolithic Pixel sensors produced in TowerJazz 180 nm CMOS technology target radiation hard applications for the HL-LHC and beyond. Several process modifications and front-end improvements have resulted in radiation hardness up to 2e15 n/cm2 and time resolution below 2 ns, with uniform charge collection efficiency across the Pixel of size 36.4 x 36.4 um2 with a 3...
The CMS detector will see the replacement of its existing endcap calorimeter with a new high granularity calorimeter (HGCAL), which will need to withstand much higher radiation levels than the present endcaps. This poses tight constraints on the front-end electronics, including the powering chain. As part of this chain, a low-dropout linear regulator (LDO) has been designed and prototyped for...
