Abstract

A multi-stage trigger processor which searches for negatively charged particles of momentum 20–50 MeV/c using wire chamber and hodoscope hit patterns is described. The five cylindrical wire chambers and a 64-fold scintillator hodoscope will operate in a magnetic field of 4 kG with an expected positive-particle background of 107/s. The last trigger stage uses the information provided by the earlier stages to calculate the total transverse momentum of the three selected tracks. The processor is implemented in FAST-BUS, making use of preloaded RAMs and look-up tables to increase speed. The design of the processor and results of extensive Monte Carlo studies are presented.
