Abstract

A front-end electronics module (FEM) has been developed for the PHENIX electromagnetic calorimeter. The FEM processes the signals received from each of 144 photomultiplier tubes and provides energy, timing and trigger information to the experiment's data collection and trigger systems. The FEM is designed to measure energies with a 14-bit dynamic range (approximately 1 MeV up to 16 GeV) with a nominal resolution of 11-bits and time of arrival with respect to the beam clock with a nominal resolution of 50 ps and an uncertainty less than 200 ps rms. Operation of the FEM is completely pipelined and should be nearly deadtimeless as data taking continues during the readout process. The FEM is also capable of forming and discriminating several energy sums with the resulting data contributing to the level-1 trigger.
