Chamber production

Production status/Material status

15.4.04 TRD Status meeting Heidelberg Clemens Adler

Production Status

• 4 week delay due to tooling

issues (winding frame, gluing table fixtures, little things here and there)

• 3 Frames glued to optimize gluing procedure.

2xL2C0, 1xL1C0

15.4.04 TRD Status meeting Heidelberg Clemens Adler

Production problems

• L-profiles are bent more than expected

-need additional clamps on gluing table.-Production is optimized

15.4.04 TRD Status meeting Heidelberg Clemens Adler

Production To Do

• Second Video measureing tableneed rails and camera holder.

• Produce wire ledge gluing toolH.Daues‘ design for TPC

• Design distance ledge gluing tool

• Start routine production(So far heavily disrupted by above mentioned problems...)

• Wiretension measuring device:Prototype from Münster was delivered last week by Holger and Damian. Need mounting, computer, infrastructure...

Production Sites

• Chamber Construc. Manual: 1st version is on the web. Please comment!!!

• Dubna: got first Material/Tooling delivery (End of March). All tooling+Material for 2 L1C0 Chambers. Next delivery is planned by Christian.

• Bukarest:Visit to Hd now (2-3 weeks) to build chambers (1xL1C0, 2xL2C0, 1xL6C1(?)). Delivery of tooling and materials upcoming.

Material Status

• L2C0 Padplanes arrived 4 weeks late:At Frankfurt for signal

cable soldering

• L6C1 Padplanes: Arrive at CERN Fri (16.4).

• L-Profiles:8 x C0 ready4 x L5/6C1 readyProduction rate: 2pc. Per day max.

• Front Profiles:22 x L125 x L2 ready.8 x L6 ready (next week)

• All other types in preparation (gluing of Wacosit to Al starts now)

15.4.04 TRD Status meeting Heidelberg Clemens Adler

Critical Issues

• Material delivery/ finishing schedule:- Padplanes- Frame profiles

• Distribution of Chamber Types:Goal: 2 Types/site

Dubna: LxC0Bukarest: L1/2C1 (+L6C1)GSI: L3/L4C1 (+xx?)Hd: L6/L5C1 (mainly)

• Alternative:

Bukarest: L1/L2C1 (poss. L6C1)

GSI: L5/L3C1Hd: L6/L4C1 (+ Test beam chambers: 3xL1C0, 3xL2C0)
