Level 1 Muon Trigger Status and Commissioning

• Rob McCroskey
• University of Arizona
• for the
• L1 Muon Group

Cabling

• L1muo trigger crates (north, central, south) are
  85 complete
• L1muo splitter crates (CFT, north, south) 30
  done - goal to finish by end of shutdown
• L1muo centroid crates (2 north, 2 south) - FE
  cables run, not hooked up
• In process of finding/fixing bad cables

Infastructure

• All production power supplies installed and
  tested
• Big thanks to Carl Lundberg for taking this
  project A-Z
• Control/monitoring GUI supplied by Manas Maity
• All rack prep done - Ed Arko Co.
• Final PORC passed!!
• Firmware written for next month of running -
  Mikhail Baturitskiy

Installed Hardware

• All crate managers - cental, north, south, and
  manager
• Trigger cards
• CF
• Five octants (0-4) CFTScint cards (05)
• Five octants (0-4) PDTScint cards (10)
• EFN, EFS
• Two octants (0-1) CFTScint cards
• Hope to add 1-2 more octants of 05 cards by next
  week
• Centroid finding cards (MCEN)
• EFN (A-layer)
• One manager card
• Four centroid cards

Triggers

• Can trigger off Aphi, CMSC coincidences in CF and
  A, B pixel coincidences currently
• Trigger is currently simple layer coicidence - no
  roads
• Plan on putting in pixel roads soon
• Working on PDT triggers currently - will start
  with simple deck trigger (e.g., 4/4 decks hit
  in A-layer)
• MDT triggers questionable - work on getting MCEN
  cards running next week and sending centroids to
  L1muo trigger cards for A-layer north

Trigger List

• 1. A.C scint coincidence central
• 2. A.C PDT coincidence central
• 3. A.B scint coincidence north
• 4. A.B scint coincidence south
• 5. A.C scint coincidence CNS
• 6. A.C scint and PDT coincidence
• 7. Central dimuon (coincidence in two central
  octants)
• 8. Anywhere dimuon (coincidence in any two
  octants)

July 1

• Assuming some short accesses, we plan on
  installing more scintillator cards (05) in both
  CF and EF
• Hardware is on hand, awaiting testing/debugging
• Everything in place for plug and play operation
• Wire boards (10) will require work - first batch
  (10/28) have some soldering problems on BGAs
• Improved scint. coincidence logic in both CF and
  EF
