High Level Trigger

• Lvl-1 trigger in construction phase now
• HLT running in processor farm immense amount of
  data generated exercising remote sites
• Detailed analysis leads to lt 400gt ms/event (on a
  PIII _at_ 700 MHz box)
• Maximum flexibility full event data available
• using offline software (very important to
  understand HLT performance)
• In terms of 2007 CPU units, this is 31.5 years
  away.
• CPU needs should be within reach
• A 50kHz system at startup will need 2500 CPUs
• N(CPU) (0.4 sec x 50000 sec-1)/(222) 20000/8

Construction Commitment Profile
Apr 02 RRB
By end of 2002 70 of the available funds will
have been committed. 62.7 MCHF of additional
funds need to be committed soon in order to have
a complete initial low luminosity detector in
2007.
22
20 MCHF Staging/Savings ?
After RRB13 the Director of Research requested
CMS to prepare plans for the case where 20 MCHF
of the shortfall is not covered (with respect to
the RRB13 shortfall of 67.9 MCHF) BUT with the
hope of getting it later. Staging/Saving already

High Luminosity Upgrades
10. Items (upgrades) for high luminosity 19
MCHF 10.1 ME4/2 mechanics and electronics
9.2 10.2 ME4/1 electronics 1.5 10.3 ME4/1
assembly in PNPI 0.5 10.4 Restore ME1/1a
electronics 1.5 10.5 Neutron Shielding
(extra) 1.0 10.6 3rd Forward Pixel
Layer 2.5 10.7 5th endcap RPC layer 2.0
10.8 Extra Installation Costs 1.0
The decision to build many of these items will
only be taken after inspection of the first
physics data. This upgrade cost comes on top of
the 62.7 MCHF shortfall. A plan for the funding
of the upgrade will have to be worked out in due
time. Basic ingredients are new collaborators or
upgrade plans by funding agencies willing to
upgrade items in which they have been working on.
25
April RRB (RRB14) Outcome
MO MoU accepted, proceed with signatures MO cat
A 2002 Budget accepted (1 MCHF with sharing
according to nb of PhDs). No request for in kind
contributions in 2002. MO Cat B Must work out a
way to share costs (by Oct RRB) CI costs
accepted (positive report by scrutiny group). CI
profile peaks in 2003. Cash flow? 50 of CI is
manpower. CMS Financial Plan well received.
Expect 54 MCHF additional funds for a shortfall
of 62.7 MCHF. Next step - Reach an agreement
with Agencies by end June 02 on likely
availability of funds (firm, less firm
promisies), amounts and time profiles. Then
prepare Financial Plan for Oct RRB (also discuss
during LHCC CMS CR in Oct02)

Conclusion
Magnet Yoke finished. Conductor and winding well
advanced. 1st coil delivered end 02 with 6 months
delay. Not critical HCAL, Endcap Muons
construction on schedule and well advanced.
Problems are being encountered but are also
being overcome. To watch Production rate of DTs
and RPCs need to watch production rate Start of
mass assembly of Si modules (Q4 2002) ECAL
Redesign of electronics chain. Very tight
schedule. Draft v33 CMS Schedule Magnet test on
surface Jan 05- Apr 05. Start lowering detector
in May 05. CMS closed ready for 1st beam 1st
April 07. CMS construction is proceeding at
speed. A low luminosity detector can be ready
for physics in 2007. The low luminosity detector
is the complete CMS detector, except the 4th
forward muon station (ME4) and the 3rd forward
pixel layer.
