- Near Detector Electronics production
- Costs
Peter Shanahan Department of Energy Review of the
NuMI Project MINOS Parallel Session Nov. 15, 2003
2Overview of 2.3 Status
- Schedule Status (BCWP/Total Budget)
- 96.7 complete
- Electronics, DAQ, and Database
- Steady progress on Data Acquisition, Detector
Control System, and Database - Thorough workout at CALDET
- Near Detector Electronics
- Near Detector Assembly of all items wrapping up
- Exceptions MINDER crate, minor clock components
- Checkout in Progress
3WBS 2.3 Accomplishments Since May 2003 Review
- MINOS WBS Milestones
- WBS 2.3.1.0.MS.7 Complete shipping for CALDET
- completed on time, 7/10/03
- WBS 2.3.0.MS.2 Near Electronics Ready for
Installation - completed 1 month early, 9/15/03 includes
equipment in use at CALDET - Successful calibration run with Near Detector
(ND) Electronics at CALDET - First time DAQ used 2 ND readout crates
- Tested Spill Mode of ND FEE, and other features
for 1st time - Assembly and checkout well along on all major
components - Exception Problem with MINDER (Front End)
Crate production
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 doesnt distinguish 50 done
from 99 done -2.3.1.0.MS.8 allows for
commissioning detector planes with electronics
long after they go in
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

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
8Near Detector Electronics Status
9MENUs
- Earlier production problems resolved
- Checkout help from IIT undergrads
- High pass rate on checkout
10CALDET
- Sept.-Oct. 2003
- 1 side of each channel read-out with Near
Detector Electronics - Tested SPILL mode (continuous data taking for
10ms) - Thorough test of system at 15 level
- Provided much feedback for diagnostics and
firmware
Time of Flight
0.5-9 GeV/c

112003 CALDET Run
- 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
lt2 - Expect improvements with full analysis
FD-ND/0.5(FDND)

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 100K favorable variance
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.
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
