P. ShanahanNov 15, 2003Page 4Upcoming Schedule Milestones
WBS Task Schedule Float
2.3.0.MS.4 Electronics Production Complete – Near 03/02/2004 248d
2.3.1.0.MS.8 Begin Near FE Electronics Installation 05/10/2004 190d
Grain of salt for Floats:
-2.3.0.MS.4 is last card completed – doesn’t distinguish 50% done from 99% done
-2.3.1.0.MS.8 allows for commissioning detector planes with electronics long after they go in

P. ShanahanNov 15, 2003Page 7Near Detector Electronics Status
• Schedule Status (BCWP/Total Budget):• 93% September 03 (85% March 03)
• Highlights• Met CALDET schedule
• MENU production and checkout nearly complete
• MASTER, KEEPER, MINDER production 98% complete* Checkout held up on MINDERs for feedback from CALDET
• Issues• MINDER (Front End) Crates
* Poor mechanical structure in 1st articles
* Apparent resolution failed to translate into production quality.
* End of CALDET travel will allow more focus on this problem

P. ShanahanNov 15, 2003Page 10CALDET
• Sept.-Oct. 2003• 1 side of each channel read-out with Near Detector Electronics
• Tested SPILL mode (continuous data taking for 10s)
• Thorough test of system at 15% level
• Provided much feedback for diagnostics and firmware

• Preliminary look at electrons in detector• Compare sum of energy
for Near Det and Far Det electronics, event-by-event
• With preliminary calibrations, ND and FD agree to <2%
• Expect improvements with full analysis

P. ShanahanNov 15, 2003Page 12Cost Variance in WBS 2.3
• WBS 2.3.1 has $384 K favorable cost variance• $994 K in May 2003 review was known to be largely artificial
* Due to statusing of production orders when placed
• Possible true favorable cost variances• Estimated ~$140K on parts and assembly in May 2003 review
* Now appears ~$100K.
• MENU Checkout * Faster, with less project labor than anticipated
* Used existing components for much of teststand systems in budget.
* Possible $100+K favorable variance

P. ShanahanNov 15, 2003Page 13Budget Overruns
• Travel for FNAL engineers and physicists to CALDET: ~$20k
• Tech and Engineer Labor• Clock system – possible c. $50k overrun
• Checkout of rest of system – implementing lessons learned from CALDET (may still be within budget)
• Other MINOR overruns
• We expect that these will be offset by true underruns.

P. ShanahanNov 15, 2003Page 14Summary
• Great progress in WBS 2.3 since May 2003 Review• Near Detector Front End Electronics reaching end of assembly
• NDFEE checkout well along
• CALDET RUN:* ND DAQ given thorough workout at CALDET
* 1st Test of beam mode for NDFEE Data taking
* Quality of data appears much better than 2003
• Overall budget appears sufficient• Need to clean up individual cost accounts for over- and under-
runs
