## Status of the FNAL Site

**US CM EMU - FNAL Site**
**CERN Dec. `98**

**Status of the FNAL Site**

**Chamber R&D **
**Engineering Status **
**Procurement Status**
**Status of Setup of FNAL Site Factories**
**Pre-Production Prototypes Schedule/Site Organization**

## Chambers - Production R&D

**Chamber Assembly**
- (Some of the) Lessons learned from P2’ Assembly:
- New Buttons for a better spacing of the Panels
- During wire winding, tension lost for ~5-10 turns after a stop.
- Gold plating on the anode bars critical for soldering
- ....plus more...
-  (check http://tdpc01.fnal.gov/uscmsemu/Meet/Oct_28_meet.html)
**Wire Quality**
- Luma vs. Sylvania	Purdue developed a “corona-effect”					device to be tested on bad D0 wire. 					Latest Sylvania quality results (from 				D0 experience) still not acceptable for 				CSC.
**Panel Cleaning**
- Machine Needs		under evaluation

## Chambers - Production R&D

**Panels  Procurement**
- New order of 14 panels received from Plascore.
- Bowing and flatness measurements being performed
- Still little cooperation from the company
- Production of the 14 panels happened without a project representative witnessing the process (contrary to the agreements)
- Very little Quality Control on the production process (no information on the panel cooling, flatness of press plates,..)
- Another test order will be submitted to open a “collaboration channel” with the company and have better control on the production process.
**Panels Machining**
- Panels bowing is not effected by the grooves machining
**On-Chamber Electrical Components Failure Rates**
- In progress. C looks OK, Anode Protection board under investigation

## Engineering Status

**Work in Progress**
**Tooling**** **
- All tooling in place for the ME23/2 chamber production. Some carts needs to be procured for the panel production.
- ME23/2 tooling has been modified for the production of ME2/1. The design of the tooling for PNPI (ME2/1 and ME3/1) is in progress and will be completed by July 1998.
- Tooling Design for Plascore QA/QC
- Building Cooling Plane for PLASCORE
- Cosmic Test Stand
- Procured and Assembled at FNAL.

## Engineering Status

**Work in Progress**
**Chambers**
- M234/2 Drawings Check
- Completed by V. Razmyslovich
- Check and finalize Engineering Drawings & generate Bills of Material
- ME23/2 design Review by January 15.
- IHEP Activity.
- “Wasted” ~2 months of engineering time on the design of ME3/1.
- Schedule pressure due to the necessity of completing  P4 (ME2/1) by summer ‘99 and therefore having the drawings ready for spring ‘99
- Will make best use of  resources at FNAL to achieve this goal.

## Procurement Status

**Major/Critical Procurements**
**PLASCORE Panels**
- Progress are slowly being made.
**Chamber Components**
- MURATA HV Capacitors are critical component (20-25 weeks of lead-time for large quantity procurements)
**Lab 8 Panel Lifting Cranes**
- 3 Vendors demonstrations
- Decision at FNAL taken on December. Waiting for money approval.
