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 5DAQ Progress and Status

• CALDET Run• Major effort for DAQ group• Experience being fed-back into planning for Near Detector

Commissioning.

• Far Detector• Data taking since 2001• Operations mode since August, 2003

• Near Detector• DAQ Workshop at RAL Scheduled for December to plan for

intallation

• FNAL Control room has been commissioned• Shifts taken for CALDET at CERN and FARDET

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
