Silicon Photomultipliers in the CMS Upgrade
A. Heering, A. Karneyeu, Y. Musienko +1
Silicon Photomultipliers (SiPM) will be used extensively in the upgraded CMS detector at the Large Hadron Collider. SiPMs have already been implemented into the barrel and endcap h…
Radiation damage studies of silicon photomultipliers for the CMS MIP Timing Detector
Y. Musienko, A. Heering, A. Karneyeu +1
Recently developed 15 um, 20 um, 25 um and 30 um cell size Hamamatsu Silicon Photomultipliers (SiPMs) were irradiated with reactor neutrons at JSI (Ljubljana) up to 2*10^14 n/cm^2…
The CMS Barrel Timing Layer: test beam confirmation of module timing performance
F. Addesa, P. Akrap, A. Albert +127
First of its kind, the barrel section of the MIP Timing Detector is a large area timing detector based on LYSO:Ce crystals and SiPMs which are required to operate in an unprecedent…
Using graph neural networks to reconstruct charged pion showers in the CMS High Granularity Calorimeter
M. Aamir, G. Adamov, T. Adams +568
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 transv…
