What and Where is CERN, LHC, CMS?
European Center for Nuclear Research (CERN)
Large Hadron Collider (LHC)
Compact Muon Solenoid (CMS)
2
CERN Airport and Accelerator
3
The CMS Detector - Subsystems
4
The US CMS Collaboration
Expected to grow to more than 500 physicists by
the start of data taking in mid 2008.

Calorimeter Cosmic Self-Trigger
US CMS has celebrated (FY06) completing 97 of
the Detector Project. Exercised the detectors in
the Assembly Hall prior to final installation in
the underground Collision Hall.
11
CMS Magnet - Status
Cooled down. Inserted HCAL late March 2006.
Field mapped by FNAL physicists
Worlds largest electromagnet 2.5 GJ
12
FNAL designed, built, and used the tools to map
13
FNAL field map of CMS good to a few parts per
10,000

UX5 (Collision Hall)
16
Final ME Chambers (ME-1/3)
Last (468th) CSC chamber installed on March 8th,
2007 at 430 pm (CERN time) End of a chapter that
started at FNAL with production of Chamber 1 on
October 1998.
17
Endcap Muon Chambers (US CMS)
Commissioned the US CMS detectors with cosmic
rays both above in the Assembly Hall and below
ground in the Collision Hall.

Packing and Shipping Half-Disks to CERN
Swiss Flight
Look at that leg room!
Dont slip now!
31
First Production Half Cylinder with Half-Disks
32
Completion of First Production CMS Pixel
Half-Cylinder at SiDET (25 of total FPIX
Detector)
Status 2nd Production Half-Cylinder shipped in
June to CERN. Currently finishing 3rd
Half-Cylinder.Expect 4th and last Half-Cylinder
to ship this autumn.
33
Remote Operations of US CMS
The LHC is a discovery machine so we must be
ready on day one. Practice data transfer and
data quality monitoring and remote data analysis.
34
Remote Analysis at the ROC (FNAL)
During the Fall, 2006 CMS Test the FNAL and CERN
ROC shared data taking shifts.

Tiered System for Data Flow

• T0 at CERN
• Record raw data and DST
• Distribute raw data and DST to T1s

• T1 centers
• Pull data from T0 to T1 and store
• Make data available to T2

CMS data sizes and computing needs require a
worldwide approach to Physics analysis. FNAL is
US CMS national computing center. There is an
LPC T2 at FNAL in addition.
