  • Eric
    • Considering to use a 3 PMT coincidence for the trigger in the RICH, but backgrounds in the RICH would give too high an accidental coincidence
    • Including alignment of hits in the RICH and LAC could bring accidentals to smaller rates
      • But his study on slide 3 assumed the LAC is triggered in a single row. If the LAC triggering is done in groups of rows, this will be more spread out
    • Some questions raised in discussion
      • Could we use smaller grouping of PMTs in the RICH (clustering?) to help reduce the accidentals?
      • How many pe's do we expect in the RICH?
