## Tracker Integration Center

- A new clean room will allow all subsystems to be integrated in acommon clean and secure area. DAQ equipment for operating up to 25% of the entire tracker will be installed. Teams from all communities will begin working together and sharing experience. US CMS will send elements of the CDF Run II team to co-lead the effort.

## FPIX - Detection Elements

**Pixel sensor wafer showing various sizes needed to form “panels”**

**Wafer of pixel readout**** ****chips**

**Pixel readout chip: 4160 pixels**
**100 x 150 ********2**

**FPIX to be re-baselined in Oct. in CMS EDR and in FNAL PMG. Team augmented by new groups from BTeV – now lead by B. Gobbi and J. Butler**

## FPIX Mechanics

- Mechanical Support of Pixel Disks

- “Cooling channel” Assembly:
- Brazed Al Parts

- 0.5 m

- Ribs between sheets
- of cc fibers

- Survey

- 18 cooling channels tested

- Service Cylinder

- Prototype meets specifications

**US CMS is intrinsic to CMS Physics organization**

## A Hierarchical Computing Model

**T0 at CERN, T1 at Fermilab as US CMS national center, **
**T2 at UCSD, Caltech, UFlorida, Wisconsin, MIT, Nebraska and Purdue as regional US CMS centers. ( + Brazil + China)**

## A National LHC Physics Center

## Remote Operations in 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. **

## LPC and Cosmic/Slice Tests

**It is important that the LPC start at the “ground floor” and connect to the detectors through the slice/magnet tests.**

## CMS in 2004, Before Cornell + BTeV

**In 2004 the US was 28% of CMS. With the addition of new groups, this % will rise because new groups are not joining from outside the US. As of today count is 31%**

## The US CMS Collaboration

**Expected to grow to more than 500 physicists by the start of data taking in late 2007. New groups (post BTeV) – Puerto Rico, Texas A&M, Rockefeller, LLNL, Purdue/Calumet, Buffalo, Wayne State, ...**

## Redirection Surveys

** ****US CMS cannot supply COLA funds for the physicists within the current RP guidance. A survey was launched after the JOG (requested by P K Williams) to sharpen the redirection numbers by asking where physicists would locate. Does a 50:50 split make sense in DOE/NSF support to US ATLAS and US CMS?**

## The FY06 “Core” Request

**Tracking – Si + FPIX has been an area of strong growth in US CMS and that is reflected in the “bottoms up” process of defining the requests and the priorities. Special thanks to PK and DOE for increasing the support to US CMS. **

## DOE+NSF Request for FY06

**The “bottoms up” process leads to a broad set of travel requests.**

## Summary

**US CMS Detector Construction is 97% complete in $ terms.**
**The tracking construction is now ramped up. Si to finish early in CY06, FPIX in early CY07.**
**Other subsystems are in commissioning mode, with cosmic ray data logged through prototype Trig/DAQ.**
**T1 and T2 are being deployed and tested in LCG Service Challenges. LCG MOU approved by RRB.**
**US CMS is heavily represented in CPT. The LPC and ROC are starting to connect to cosmic ray data taking, DQM and analysis.**
**US CMS is growing rapidly in anticipation of first beam in CY07.**
