**Trigger/Keeper**

**MINDER**
**modules**

**MASTER Crate**

- Component Count (not counting ~10% spares):
- 9328 MENUS
- 583 MINDERS
- 81 MASTERS

## 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

## MENU Production Problems

- Sporadic production startup:
- Fabrication
- Solder on gold contacts – not noticed until fabrication began.
- Vendor has accepted responsibility: inspection+new 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 >90%
- 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

- Spares (~10%) not included in this table.  Various Auxillary cards not included

- All modules have CALDET quantities met

## Summary

- Near Electronics Production is Well Underway
- All boards in assembly (or done!)
- CALDET quantities are met
- Thorough Checkout in progress at Argonne, FNAL
- IIT help on MENU checkout
- Production appears well on schedule for detector installation
