## Status of the FNAL Site

**US CM EMU - FNAL Site**
**G.Apollinari - Lyon Sep. `98**

**Status of the FNAL Site**
**(also visit http://tdpc01.fnal.gov/uscmsemu)**
**Chamber R&D **
**Engineering Status **
**Procurement Status**
**Status of Setup of FNAL Site Factories**
**Pre-Production Prototypes Schedule/Site Organization**

## Chambers R&D

**Chamber Assembly**
- Need:
- Evaluation of flatness
- Plane Gap Uniformity (+/- 12 mils)
- Dry Assembly of M234/2 Pro-production Prototype
- Test of Assembly Table
- Chamber Deflection in Horizontal & Vertical Position
- Effects on Plascore Specifications
**Wire Quality**
- Luma vs. Sylvania	just started, presentation on D0 gold 				flaking problem
**Panel Cleaning**
- Machine Needs		in progress

## Chambers R&D

**Panels  Measurements**
- Panels flat of a 5x10 granite table under their own weight
- Measured bowing in the y (acceptable) and x (un-acceptable) directions

## Chambers R&D

**Chamber Sagging**
- Final Assembly
- bottom panel straight (~5 mils)
- top panel sags (70 mils)

## Chambers R&D

**Chambers R&D**

**Chamber Sagging**
- Buttons-Gap Bars difference

- ~374 mils

- Still ~30 mils
- unexplained

## Chambers R&D

**Panels Deformation**
- We believe the PLASCORE panels we are working with have a ~1/32” (20-30 mils)  bow in the 5’ direction
- String Measurements on free standing panels.
- Laser Tracker measurements on granite table (see slide)
- Under gravity, for a single panel sitting on the gap bars
- Q: Which kind of force is a sagging panel exerting on the next lower 	   panel through the button ?

- Sag (~40 mils)

- Sag (~0 mils)

## Chambers R&D

**Panels Deformation**
- Measured the displacement vs. force for a panel surface by pulling or pushing close to the button hole location (for both orientations of a panel).
- For small displacements: ~ 1 lb./1 mil elastically
- Q: Which kind of deformation do we have close to a button hole for 	   forces of the order of 10-20 lb. ?
- Instron Measurements at TD Material Lab

## Chambers R&D

**Grooves Depth**
- Issue
- Avoid “skips” during the machining of the panels
- Grooves of different depths are exposing approximately the same amount of G10 fibers
- Panels with grooves of different depths have the same mechanical strength.

## Engineering Status

**Work in Progress**
**Tooling**** **
- Finalization of Carts Drawings and Assembly Tools
- Gerber and Axxion transport cart
- In-process Panel Trans. & Solder
- Chamber assembly Table
- Chamber Transport and RTV Gas Sealing Cart
- Tooling Design for Plascore QA/QC
- PLASCORE had no in-process QA capability
- Release for Procurement of the Cosmic Test Stand
- FNAL & FAST Sites

## Engineering Status

**Work in Progress**
**Chambers**
- M234/2 Drawings Check
- Completed by V. Razmyslovich
- Check and finalize Engineering Drawings & generate Bills of Material
- Started Activity on IHEP. PNPI drawings expected by mid Oct. 98

## Engineering Status

**Goal**
**Engineering Drawings completed and released for ME234/2 by Dec. 98**
**Plan**
- Receive Wisconsin frames drawings by end Sep. 98
- Integrate Chamber Frames in Oct. 98
- Ready to proceed for the release pending approval by L2.
- Estimate 2-3 weeks for implementation of engineering changes
**November EDR**
- Presentation of the current status, including all the information provided to FNAL

## Procurement Status

**Major/Critical Procurements**
**PLASCORE Panels**
- Requirements and  Specifications Understood..** **
- Available Panels:
- Fail our specs in a “single panel” measurements on a granite table.
- Sagging problems in “gap bars constrained” configuration prevented us from measuring a 10 mils bowing over 2 feet.
- the Receive Wisconsin frames drawings by end Sep. 98
- Visit to PLASCORE (Aug. 98):
- PLASCORE has no tooling for QC. FNAL will provide it (~ Sep. ‘98)
- PLASCORE identified 3 areas of possible improvements:
- Core Cutting on 5 feet wide table
- Core Thickness measurement
- Control of the area of pressure on the Gluing Press
- Will order 14 panels with the above-mentioned improvements

## Procurement Status

**Major/Critical Procurements**
**Wire **
- Specification writing based on D0 experience.
- R&D on 1-2% Gold-Tg SYLVANIA wires.
- R&D of flaking gold ? Which QC/QA does LUMA apply ?
- Good QA Plane needed.
**Panel Cleaning Machine **
- Impossible to do R&D on final chamber
- Will make systematic measurements on interstrip resistance and water retention on sample panels.

## Pre-Production Schedule

**Pre-production Milestones**
- ME234/2  pre-production chamber ready		Nov. 16  `98
- ME2/1 pre-production chamber ready			Dec. 8    `98
- All pre-production chambers produced at MP9, with the final tooling and training the final assembly crew.
