Near Detector Electronics Status

• Schedule Status (BCWP/Total Budget)
• 88 (April 03)
• All WBS 2.3.1 system components are in production
• Problems with MENU startup
• All Printed Circuit boards in Assembly phase (or
  done)
• Thorough checkout in progress
• All power supplies received/ crates in progress
• WBS 2.3.6
• Auxillary systems (timing)
• Minder Timing Modules, Clock Fanouts, Master
  Clock Controller done
• Redesign of VME Timing Module for flexibility

MENU Production

• Front-end daughter card
• Supports and reads out QIE
• Stores digital data in pipeline
• 9328 in system
• 1440 plus spares required for CALDET

5
MENU Production Problems

• Sporadic production startup
• Fabrication
• Solder on gold contacts not noticed until
  fabrication began.
• Vendor has accepted responsibility
  inspectionnew boards
• Vendor inspection insufficient (no microscope on
  QC line!)
• Assembly
• Incorrect 1st articles
• Overheated burn-in by vendor on 200 boards
• Poorly tuned initial automated optical inspection
  by vendor
• Wrong solder flux on several hundred boards
• All problems addressed by vendor
• Production has finally reached steady rate with
  consistent quality
• Much effort on 14th floor Lou Dal Monte, Merle
  Watson, Charlie Nelson

MENU Good News

• 5000 boards in hand
• Checkout rate of boards with no acute problems is
  gt90
• Assumed 67 in checkout schedule
• Thorough checkout of all MENU functionality
• IIT Undergrads for Checkout
• Resident at FNAL for 5 weeks
• Will later take test-stand to IIT
• Very helpful in meeting CALDET schedule
• Long-term production
• Rate of 330/wk will complete production by
  12/31/03

Argonne Checkout

• MINDERS, MASTERS, KEEPERS
• Minders loaded with MENUs
• Full system tests
• Dave Reyna Pedestals, DC Calibration
• Tests virtually all aspects of the entire
• system
• Lower Level Testing
• Gary Drake, Bill Haberichter, Tim Cundiff, et al.
• Testing all bits, reading/writing all registers,
  etc
• Checkout done with a few sets of PROMs
• Final PROMs will be burned post-CALDET
• Shipping for CALDET in progress

2003 CALDET Run

• Sept. 4 Oct. 4, 2003
• 1440 channels on Near Detector Electronics
• Full instrumentation of 1 side (actual ND is one
  sided)
• Near only, and Near/Far running
• Production calibration of Near response
• ND Electronics is principle focus of run
• Ship electronics in late June
• L3 milestone 7/7/03
• Move to beam enclosure 8/18/03
