The front-end electronics upgrade of the CMS ECAL barrel

The barrel part of the CMS electromagnetic calorimeter (ECAL) consists of 61200 PbWO$_4$ crystals coupled to avalanche photodiodes (APDs). A decrease of the ECAL operating temperature from 18$^{\circ}$ C to 9$^{\circ}$ C is needed to mitigate the increase in APD noise from radiation-induced dark cur...
