Title: MINOS WBS 2.3: Electronics, DAQ and Database


1
  • MINOS WBS 2.3 Electronics, DAQ and Database
  • Status
  • Accomplishments since May. 2003 review
  • Near Detector Electronics production
  • Costs

Peter Shanahan Department of Energy Review of the
NuMI Project MINOS Parallel Session Nov. 15, 2003

Overview 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

WBS 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

Upcoming 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

DAQ 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

Near 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

Near Detector Electronics Status

MENUs
  • Earlier production problems resolved
  • Checkout help from IIT undergrads
  • High pass rate on checkout

10
CALDET
  • 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
  • p,m,e,p

0.5-9 GeV/c

2003 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)
P (GeV/c)
FD-ND/0.5(FDND)
P (GeV/c)
Known miscalibrated channel causes this shift
FD-ND/0.5(FDND)

Cost 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

13
Budget 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.

14
Summary
  • 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
