Abstract :
Summary form only given. The electronics of the 13000 photomultipliers of the high-resolution ZEUS calorimeter is described. It consists of pulse-shapers 10-MHz-5- mu s analog delay lines, analog buffers, multiplexers, and VME-ADC (analog-to-digital converter) cards. Digital signal processors on the ADC cards apply correction constants and reconstruct charge and time from the digitized voltage samples. The system achieves a dynamic range of 16.5 b and a time resolution below 1 ns.<>
