-The main purpose of the trigger is to implement a coincidence between the S800 focal-plane fast timing scintillator [[Detectors#Plastic scintillators|E1]] and a secondary detector principally located at the target location. This coincidence is often a mandatory requirement when the trigger rate of the S800 alone (S800 singles) is too high for the data acquisition and the resulting dead time is prohibitive.

 The trigger logic is implemented in a LeCroy 2367 Universal Logic Module (ULM) by means of its XC4000E Xilinx FPGA. The main motivations for implementing the trigger logic in an FPGA driven module are the following:
