โœฆ Synopsis

ESOP is a fast processor designed to front-end the data-acquisition computer in high energy physics experiments and perform second level trigger calculations. It is in use in five experiments at CERN and Saclay. It will be shown how ESOP realises its high performance and how such a machine may he supported in an experiment. For trigger calculations the efficiency of the connection to the detector read-out system is extremely important and the ways in which this is done in practice with ESOP will be discussed. An outline of some existing trigger algorithms will be given and some conclusions drawn on desirable features of a second-generation processor based on experience with ESOP.

A fast special purpose processor as a part of the trigger logic in an elastic scattering experiment is described. The decision to incorporate such a processor was taken because the trigger rate was estimated to be an order of magnitude higher than the data taking capability of the on-line minicomput
