Using graph neural networks to reconstruct charged pion showers in the CMS High Granularity Calorimeter / CMS HGCAL Collaboration
A novel method to reconstruct the energy of hadronic showers in the CMS High Granularity Calorimeter (HGCAL) is presented. The HGCAL is a sampling calorimeter with very fine transverse and longitudinal granularity. [...]

Timing Performance of the CMS High Granularity Calorimeter Prototype / CMS HGCAL Collaboration
This paper describes the experience with the calibration, reconstruction and evaluation of the timing capabilities of the CMS HGCAL prototype in the beam tests in 2018. The calibration procedure includes multiple steps and corrections ranging from tens of nanoseconds to a few hundred picoseconds. [...]

Neutron irradiation and electrical characterisation of the first 8” silicon pad sensor prototypes for the CMS calorimeter endcap upgrade / CMS HGCAL Collaboration
As part of its HL-LHC upgrade program, the CMS collaboration is replacing its existing endcap calorimeters with a high-granularity calorimeter (CE). The new calorimeter is a sampling calorimeter with unprecedented transverse and longitudinal readout for both electromagnetic and hadronic compartments. [...]

Performance of the CMS High Granularity Calorimeter prototype to charged pion beams of 20–300 GeV/c / CALICE Collaboration
The upgrade of the CMS experiment for the high luminosity operation of the LHC comprises the replacement of the current endcap calorimeter by a high granularity sampling calorimeter (HGCAL). The electromagnetic section of the HGCAL is based on silicon sensors interspersed between lead and copper (or copper tungsten) absorbers. [...]

Response of a CMS HGCAL silicon-pad electromagnetic calorimeter prototype to 20–300 GeV positrons / CMS HGCAL Collaboration
The Compact Muon Solenoid Collaboration is designing a new high-granularity endcap calorimeter, HGCAL, to be installed later this decade. As part of this development work, a prototype system was built, with an electromagnetic section consisting of 14 double-sided structures, providing 28 sampling layers. [...]

The DAQ system of the 12,000 Channel CMS High Granularity Calorimeter Prototype / CMS HGCAL Collaboration
The CMS experiment at the CERN LHC will be upgraded to accommodate the 5-fold increase in the instantaneous luminosity expected at the High-Luminosity LHC (HL-LHC). Concomitant with this increase will be an increase in the number of interactions in each bunch crossing and a significant increase in the total ionising dose and fluence. [...]

Construction and commissioning of CMS CE prototype silicon modules / CMS CE Collaboration
As part of its HL-LHC upgrade program, the CMS Collaboration is developing a High Granularity Calorimeter (CE) to replace the existing endcap calorimeters. The CE is a sampling calorimeter with unprecedented transverse and longitudinal readout for both electromagnetic (CE-E) and hadronic (CE-H) compartments. [...]

CATIA: APD readout ASIC for CMS phase 2 ECAL electronics upgrade / Gevin, Olivier (IRFU, Saclay) ; Baron, P (IRFU, Saclay) ; Dejardin, M (IRFU, Saclay) ; Guilloux, F (IRFU, Saclay) /CMS Collaboration
The incoming LHC upgrade to HL‒LHC calls for a change of the ECAL front-end electronics design in order to maintain the present performance of the detector while facing a higher instantaneous luminosity and to optimize the timing resolution while using the existing crystals and APDs. The design of the new front-end electronics is based on the cascading of two ASIC: a fast, dual gain trans-impedance amplifier designed in a 130 nm CMOS process (named CATIA) and a dual ADC designed in a 65 nm CMOS process. [...]

Performance of CATIA ASIC, the APD readout chip foreseen for CMS Barrel ECAL electronics upgrade at HL-LHC / Baron, Pascal (IRFU, Saclay) ; Dejardin, Marc (IRFU, Saclay) ; Gevin, Olivier (IRFU, Saclay) ; Guilloux, Fabrice (IRFU, Saclay) /CMS
The CMS ECAL barrel electronics will be upgraded for the HL-LHC to meet the latency and bandwidth requirements of the Phase-II Level-1 trigger system. The new front-end electronics will mitigate the increasing noise from the avalanche photodiodes (APDs), discriminate against anomalous APD signals and provide improved timing information. [...]
