Upgrade of the readout electronics of the Liquid Krypton Calorimeter at NA62 Experiment

CERN SPS (Super Proton Synchrotron) send particles to the NA62 experiment to study kaon decays with precision. The Liquid Krypton Calorimeter (LKr) was built previously for the NA48 experiment, and now is an important part of the veto system. To get results of high precision, its electronic chain has been in constant update. This report presents an upgrade of the electronic chain of the LKr, specifically, on its shaper and transceiver, with the purpose of improving the time response.
