  1. David --- no update
  2. Simona --- continuing to test PMTs, does not need DAQ support yet
  3. Jan --- no update
  4. Paul --- no update
• 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?
