## Background Considerations

**Of the ****5 chamber types**** only **_**ME23/2**_** (largest chamber) will be assembled at Fermilab in ****MP 9****.**
**A quantity of ****144 + 2**** spares chambers of this type required....**
**	****	****4 Chambers completed as of 7/1/00.**
**Goal - To complete production in June, 2003 - ****3.0 years****.**
- Must Complete 74 chambers by Jan. 2002

## Changes Since Last Review

**Responsibility for Frame Design and Procurement *****moved*****  from UWM to Fermilab.   Means added Resources Required to Complete Designs, Procurement, Inspection and Kit Preparation**
**Added New Wiring Harness with 19 Pin HV Connectors to Replace 7 and 13 Pin Connectors **
**Frame features modified to accommodate New HV Connector Wiring Harness, Electronics Cooling Plate, and Cathode Cable Strain Relief**
**Ground Lugs added to Panels at each Strip Connector**
**Retro-Reflective Targets and Alignment Strips added to Inner Cathode Panels (2 on wide end & 2 on narrow end)**
**Gas fittings added to Bulkhead Connectors**
**Bleed Resistors (SIP’s) added to Ground Strips**
**Modified Anode Side Panels (added holes) and Anode Protection Boards (removed latches) to Accommodate Anode Front End Circuit Cards**

## Design, Drawing Statusand Configuration Control

**All ME234/2 Chamber Drawings have been Updated to Include ****Requested Design Changes**
**Revised Drawings Have Been Circulated, Reviewed, and ****Approved by All Level 2 and 3 Managers, and Responsible  Sub-Groups Representatives**
**Revised ME 234/2 Chamber Drawings Reflecting Requested Design Changes ****Now in Engineering Release Process**
**Signed Travelers have been Updated to Accommodate Design Changes**
**In Accordance with ****Project Management Plan****, the ****Product Configuration Change Specifications**** Describing the Approved Design Drawings have been ****Approved and Signed by All Required Level 2 and 3 Managers**
**All Needed Tooling is Available and Operational To Meet Short Term Schedules;  Additional Tooling On Order to Meet Full Production Rate**

## Lab 8 Manpower

**Panel Production Rate is Met with the Planned 2.4 FTE Rate**
**Current Rate is Down due to Loss of Valued Worker**
**Adequate Supply of Finished Panels (50%of Required) to Meet Production Needs**
**Some Catch-up May Be Required if Delays Persist**

## MP9 Manpower

**Current Labor Force at 5 Technicians**
**Two Chambers Essentially Produced in June with 4-5 Technicians**
**Will Grow to 7 Technicians by  November, 2000**

## Materials Control Plan

**Procurement, Inventory, Inspection, and Kit Preparation for ****Frame Parts**** in addition to other Chamber Parts now Responsibility of TD Materials Control Group**
**One FTE to be Added to IB4 Group to Handle Inventory and Kit Preparation**
**One Half FTE for 2 years to be Added to Procurement Group to Handle Additional Frame Load**

## Concerns and Pending Changes

**Alternate High Voltage Connectors are being Considered**
**Decision to be Made by End July**
**Estimated Cost ~50% of Baseline**
**Readily Available - CERN Can Produce**
**Production Testing of Chambers May Continue Without High Voltage Harness **
**Minor Additional Work Required to Add Harness Later**
**Frame Extrusions Must Be Procured Soon**

## Summary and Conclusions

**Four Chambers Successfully Completed Using Only Production Tooling Consistent With Configuration Requirements**
**All Materials Available To Continue Production;  Available Tooling is Adequate with Additional Tooling Ordered to Accommodate Ramp Up **
**Current Staff and Hiring Plans are Adequate to Meet Production Needs**
**All Technical Documentation (Drawings, Specifications, and Travelers) In Place and Being Used**
**Ramp Up Requirements Understood and Addressed**
