1. Overview

The following documents and information form the basis of the UK-B request to be approved for Series Barrel Module Production. They are provided below in the format from the Site Qualification Needs Document:

For the UK-B Barrel Module project

Cluster Responsible:	A Carter
Cluster Quality Control:	D Charlton

Qualified teams exist for module assembly and metrology (RAL), hybrid assembly (Birmingham) and electrical testing (all UK-B institutes):

RAL: P Adkin, R Apsimon, P Booker, J Bizzell, V Davis, J Easton, C Fowler, S McMahon, O Morris, PW Phillips, M Tyndel, G Villani
Birmingham: P Bell, D Charlton, B Gallop, P Jovanovic, S Pyatt, X Serghi, J Wilson

Details of RAL work can be seen in this document (MS-Word format).

An overview of the UK-B module QA is given in the Outline of UK-B Module QA activities document (MS-Word format).

2. Steps to have been Completed

Production of 5 electrical modules, satisfying every aspect of the electrical and mechanical specifications listed in SCT-BM-FDR4 and SCT-BM-FDR7. For the summary, including yield, see:

4. Required Facilities

The appropriate facilities are now in place at each of the 4 institutes, and include:

inert gas storage for components and completed modules available at all UK-B cluster sites
appropriate glue storage is implemented as required at RAL and Birmingham
a clean room for module assembly equipped with all necessary wire bonding, module assembly station, glue dispensing, metrology station is in use at RAL; a clean room is also in use at Birmingham for hybrid assembly and bonding, and at Cambridge and QMUL for semiconductor testing.
a jig set has been commissioned for all processes in module assembly and 5 further sets are in production
database terminals and barcode readers are in use at all UK-B cluster sites
hardware and software for module QA as listed in SCT-BM-FDR7 is in use
appropriate insurance cover has been applied for by all institutes concerned. It is already in effect in the universities.
