Radiation Testing of New Readout Electronics for the CMS ECAL Barrel
/ Harringer, Nico (Zurich, ETH) ; Dissertori, Gunther (Zurich, ETH) ; Gadek, Tomasz (Zurich, ETH) ; Wojciech Hajdas ; Haller, Christian (Zurich, ETH) ; Loukas, Nikitas (Notre Dame U.) ; Lustermann, Werner (Zurich, ETH) ; Morvaj, Ljiljana (Boskovic Inst., Zagreb) ; Singovski, Alexander (Notre Dame U.) ; Stachon, Krzysztof (Zurich, ETH)
In preparation of the operation of the CMS electromagnetic calorimeter (ECAL) barrel at the High Luminosity Large Hadron Collider (HL-LHC) the entire on-detector electronics will be replaced. The new readout electronics comprises 12240 very front end (VFE), 2448 front end (FE) and low voltage regulator (LVR) cards arranged into readout towers (RTs) of five VFEs, one FE and one LVR card.

The barrel section of the novel MIP Timing Detector (MTD) will be constructed as part of the upgrade of the CMS experiment to provide a time resolution for single charged tracks in the range of $30-60$ ps using LYSO:Ce crystal arrays read out with Silicon Photomultipliers (SiPMs). A major challenge for the operation of such a detector is the extremely high radiation level, of about $2\times10^{14}$ 1 MeV(Si) Eqv. [...]
