Activities

Our group is primarly involved with the Silicon Vertex Detector and the DIRC Particle Identification Detector.

Silicon Vertex Detector

Test Beam Module

Here is information about the Layer 2 module that has been assembled for the May '97 test beam at CERN. There are a number of pictures of the assembly sequence and a spreadsheet of the bonding map, faults, noise and gains of every strip. (April 1997)

Test Beam Analysis

Information on the testbeam analysis can be found here. (October 1997)

Prodution Wirebonding and Testing

This page shows information relating the DFA Production. (Status, summaries, bonding maps and documentation)

HDFA Production

Status of gluing, bonding/testing, and assembly of first six sextants and modules
Accounting of H1 usage
Accounting of H2 usage
Overview of MS Project for first 6 sextants and layer 3 modules
