Very Front End (VFE) Electronics

• New version of FPPA received Dec 02. Faults
  corrected but noise 30 higher than spec, yield
  35 (instead of 50). Very Front End analogue
  electronics still a concern.

ADC and MGPA DSM Chips

• Alternative New 0.25mm (DSM) ASICS, preamplifier
  (MPGA) ADC submitted Feb 03, expect packaged
  chips in May.
• DSM front-end expected to be substantially
  cheaper, consume less power and have slightly
  better performance
• DECISION in mid-2003 after comparative tests of
  alternative systems
• Prototype of VFE cards ready to test both
  versions

  Memories (2 ns scale)

Trigger L2 manager is Smith U. Wisconsin.
Second round of prototypes. Trigger will supply
portable system for SX5 slice tests.

Trigger Transition to MO

• Installation in UndergroundCounting Room
• Expect access by March 05
• Sufficient time for installationand some testing
  but not forcompleting commissioningwith
  detectors
• Need to startcommissioning earlier
• Slice Test (on surface)
• With Both HCAL and EMU
• Verify trigger functions and interfaces by
  testing with detectors on surface at CERN.
• Use as substitute for commissioning completion
  step.
• Will check as much on surface before gaining
  access to underground facilities.
• Milestone (HG1018) planned for completion
  November 04

21
Trigger Tables

• Level-1 Trigger at low luminosity (2?1033cm-2s-1)
• Total Rate 50 kHz. Factor 3 safety, allocate
  16kHz

Tables exist for 1/5 and design L. Discovery
modes covered well. We think we know how to
trigger CMS and acquire the Physics.
22
CMS Data Acquisition
DAQ TDR submitted end-02 Modular design of Event
Builder
8 x (12.5 kHz DAQ units)
The single-farm design, that provides maximum
flexibility in the physics selection, works.
23
US-CMS Data Acquisition

• Next major milestone - Dec. 2003
• Event Builder Preseries and DAQ slice ready

• Work focussing on
• front end drivers and links
• integration and event building software
• event manager

This system will be used for the detector slice
tests. US will build first 1/8 of DAQ. ODell
FNAL is the L2 manager.

Recent Events Calendar -I

• Last 6 months relevant events
• CMS Week, Sept. 21, 2002 - scheduled confirmed
  for first beam in April, 2007
• AR (CMS)
• CR (LHCC)
• Oct. 1 - DOE/NSF Quarterly Status Review - no
  major issues

Invent slice tests for pre-ops in ME, HCAL,
Trigger and DAQ. Minimize the time before getting
Physics results
27
LHC - SUSY
Energy matters! One month at 1/10 design
luminosity extends mass reach by a lot. LHC
experiments must be ready on week one for new
Physics. That perception defines the US CMS
strategy of slice tests in SX5 of ME and HCAL
with a portable trigger from the US and with a
portable DAQ since the US supplies the first
1/8 of the DAQ a stand alone segment.
28
LHC - SM Higgs
The LHC detectors are designed to find the SM
Higgs. Low mass is covered by ??, ttH(bb),
qqH(WW,??). A low mass Higgs has many
accessible decay modes ? couplings measured. Plot
is 4 months at design luminosity.
29
Detector Project - Endgame
The US CMS detector deliverables will be 96
complete in FY05 and finally installed in UX5 by
FY07. The BA has evolved to reflect this fact.
The Detector Project is over by FY05. The
softer profile allows US CMS to maintain the SWC
effort at a flat level in FY02 through FY04.
30
Calendar - II

• ICFA, Oct. 8 - SLHC. Plans for 10 x in Luminosity
  by detectors and accelerator shown publicly.
• RRB, Oct. 19 - CRRB initiated. LCG as a distinct
  request. Keep in the context of CMS - single
  point of contact.

31
Calendar - III

• SCOP ,Oct. 24 - external review of US CMS SWC.
• ITR , Nov. 12 - LITR and MITR, joint US ATLAS/US
  CMS NSF proposals. Attempt to get more funding
  into SWC work.

32
Calendar - IV

• CMS Week, Dec. 2 - status.
• SWC Review, Jan. 16 - LBNL. NSF guidance firms
  up. NSF begins to advance the ramp-up of the RP.
• P5, Jan. 28 - US LHC status. well received gt
  high priority.
• P5, Feb 15 - HEPAP Facilities. US LHC gets
  highest priority for SLHC (LC and SNAP too)

33
Calendar - V

• CMS Week, Feb. 24 - status
• JOG in Washington, Feb. 24 - Discussion of RP.
  DOE cuts 2.5 M in 2004 from previous guidance.
• HEPAP at LBNL, March 6 - LHC Collaboration Group
  presents LHC status
• LITR submitted, March 14

34
Calendar - VI

• FNAL DOE Review, March 18 - US CMS status.
• P5, March 26 FNAL affirms that US CMS is a high
  priority item in their research program.
• FNAL PAC, March 28 - Status of US CMS and physics
  reach. US CMS is a part of FNAL program.

35
Calendar - VII

• LHC Collab Group at NSF, Apr. 4 - well received,
  funding schedule ramp up confirmed.
• MO Review, April 8 baselined. Therefore
  start VCR and PAC. Scrubbed MO hard -
  Nevertheless, retain 3 Tier - 2 PAC.

36
Current RP Guidance from DOE/NSF
US CMS was instructed to plan scope to fit inside
this guidance.

38
Issues

• The ramp up of the RP is crucial. FY03 and FY04
  will either get us a good start on preparation
  for Physics or we will drop the ball on Data
  Challenges and the Physics TDR.
• A firm commitment by NSF and DOE is absolutely
  necessary if we are to plan rationally. The MO
  Evaluation Group and SWC Reviews are a good start.

39
Summary

• Technical Progress has been good.
• Schedule has been maintained for April 07 first
  beam.
• Financial progress has been steady. Scope
  continues to be increased.
• The Project will end in FY05 with CD4-a.
