摘要：

The SeaQuest experiment (Fermilab E906) detects pairs of energetic p and p produced in 120 GeV/L.' proton-nucleon interactions in a high rate environment. The trigger system consists of several arrays of scintillator hodoscopes and a set of field-programmable gate array (FPGA) based VMEbus modules. Signals from up to 96 channels of hodoscope are digitized by each EPGA with a 1-no resolution using the time-to-digital convertor (TDC) firmware. The delay of the TDC output can be adjusted channel-bychannel in 1-no step and then re-aligned with the beam RE clock. The hit pattern on the hodoscope planes is then examined against pre-determined trigger matrices to identify candidate muon tracks. Information on the candidate tracks is sent to the 2nd-level FPGA-based track correlator to find candidate di-muon events. The design and implementation of the FPGA-based trigger system for SeaQuest experiment are presented. (C) 2015 Elsevier B.V. All rights reserved.
