22
Detector Project Summary

• Recent reviews Detector June 5-6, FNAL
  Technical Review April 29-May1, MO Review April
  11.
• MS cost experience has been good.
• The labor for CSC and HCAL absorber/optics has
  been fairly well estimated. Chambers and
  absorber/optics are done.
• We are in the midst of FE electronics production
  no cost or technical surprises (yet).
• Contingency use has been good enough to allow for
  modest scope increases SiTrkr, HE, HF, ME1/1,
  ME VME (US CMS management)
• It is logical to define the end of the Project to
  be completion of deliverables prior to slice
  tests in SX5 for commissioning.

27
Project Completion

• It is logical, given the discontinuity between
  SX5 and UX5 installation, to define Project
  complete as SX5 installation. This can be done by
  FY06 end.
• MO begins with commissioning and preops in SX5
  in FY03.
• Final installation, costing 8 M, could be a
  distinct effort.

28
US CMS Resources
Note the rolloff of construction to MO by FY05.
The major category for MO is physicists -gt base
program.
BaBar Reality check
29
US CMS Commitments
Total MO ramps up slowly as the detector
construction is completed. The ramp is the sum of
L2 handoffs.
30
L2 Commitments
Each L2 has a different schedule to complete the
detector and handoff to MO
31
L2 - Scrubbing
In scrubbing the costs engineering was released,
reducing scope, on the assumption that FNAL
personnel can be recaptured. In other cases,
knowledge transfer and consolidation was assumed.
This procedure carries serious risk. Tasks were
also somewhat delayed, which reduces schedule
float and risks discontinuity with the
construction team. Some costs on a fuzzy boundary
were shifted onto the construction project, which
reduces the project contingency.
32
CO (Cat A) PO Costs
WBS 18 CO is 69 CatA bills. The Ops Office
is comparable to the PO, with a new CERN branch.
PO is extended to ease MO costs (but NSF FY04).
33
Handoff to VCR, PAC
The estimated costs have been scrubbed. For
example, beyond paying the bills, there are few
costs prior to FY05. Then the VCR and PAC ramp up
to pace the detector slice tests and the data
challenges.
34
Management Scrub
CO is Cat A, OM delay (use PO), RD delayed, MR
10 in FY02-FY05. This reduction means management
is rather less agile and detector is taxed.
35
MORD Cost Estimates
36
SWC Tier 1,2 in the US
CERN financial problems are an opportunity for
the US to step forward and lead.
37
Preparing for First Beam
Need to keep in synch with CERN, LHC, and CMS
schedules
38
Status and Progress
Common PO economy of scale
39
User Facilities Status
UF needs to be augmented
40
Prototype Operation
41
Bare Bones SWC

• There has been a top down re-estimate of FY03 and
  FY04 needs.
• Basically, CCS is constant and UF is ramped up
  very little. This puts the mock data challenge at
  risk.
• Revised planning at SWC status meeting June 21.

42
Research Program Costs
Having scrubbed hard, and perhaps having
overshot, US CMS remains 2 M above guidance
for FY03-FY05.
43
Research Program Scrub

• We have scrubbed the estimates
• RD is delayed gt FY05, Reserve is only 10
• PO is stretched to delay OM
• L2 costs are pushed onto Construction or are
  delayed, as possible
• SWC, UF ramp up is minimal in FY03, FY04
• The reduced costs are still 7 M above guidance.
  We cannot cut harder without serious risk.

44
Issues

• We need help in defining the end of detector
  construction. Declare victory upon receipt of
  MOU deliverables?
• We need help in more rapidly starting up the
  Research Program which is now back loaded. After
  vigorous scrubbing, the needs are still above
  guidance.
• We need a commitment by NSF in support of the US
  CMS Research Program at least at the 1/3 level
  assumed in our planning.

45
Summary

• The physics at the LHC is compelling.
• The transition of the detector project to the
  Research Program begins in FY02.
• The SWC , MO, and Upgrade RD components of the
  Research Program all have resource loaded
  schedules which are being scrubbed.
• The Research Program will enable US physicists to
  make a major impact on CMS, if it is properly
  funded.

46
Contingency Usage and Performance
We have 47 months of monthly reporting. CR can be
followed at any level of detail needed.
Contingency continues to be earned.

WBS 19 Ops Office
There is an NSF branch which opens in FY04, and
a CERN branch which is integral to MO.
55
MO RD at L2
The major cost drivers for US CMS are HCAL, EMU
and Common Ops, totaling 2/3. Common Ops
Operations Management are 1/3 of the total.
56
Scrubbing Results
Both the scope has been reduced and the tasks
have been delayed. Both effects have risks to
the US CMS institutional memory

FNAL Technical Review

• There was a Directors Review on US CMS, April
  30.
• External Committee looked at ME, HCAL and Trigger
  electronics production. In addition review
  covered FPIX and SiTrkr status and progress, both
  Si itself and the associated electronics.
• There was general agreement about the areas of
  concern.
