The function of a PMT block is to convert light signals from the calorimeter cells into electronic signals. Each PMT block contains a photomultiplier tube, a light mixer which serves as the interface between the PMT and the fibre bundle, a high voltage divider and a 3-in-1 base which is the interface with the electronics read-out.
