1. Hd Status and Planning TRD Chamber Construction Meeting 27.2.06 Clemens Adler

2. Hd Status 4 L0C1 chambers for 1st SM (almost) finished 2 L0C0 chambers finished (1st + 2nd SM) 1 new Technician (for 6 month) in for chamber building/profile production Most manpower is going into SM assembly currently.

3. Regular Chamber Meetings Discussed with Yuri, Mihai and Christian: Have a regular meeting few days before status meeting, via Video/Skype dedicated to chamber construction issues Place: GSI/Frankfurt/Heidelberg?

4. Material Ordering Reminder: –Make sure you know 2-3 month ahead what you need (1-2month for shipment/customs +delivery times) –(Front/L-)Profiles are coming from Heidelberg (Clemens) Padplanes from Frankfurt (Wolfgang) Glue, Wire, etc. from GSI (Christian Lippmann) ‘Need something very urgently’ produces delays for other Labs (currently anode wire is a bottleneck)

5. Database Data will have to migrate to DCDB (probably soon) Preparing a simple Database HowTo Some changes will happen to DB (e.g. anode/cathode wire roll number to be entered for a chamber) Entering Chamber information is required (every part with a serial number)

6. Leakrate O2 time constant to be recorded? At least make a note (on chamber + in Database (comment))

7. Testing of chambers after Transports Bucharest /Dubna chambers will be tested after transport for leak rate (N2), HV test in air/N2. Will be tested at Heidelberg (Clemens). Future procedure to be defined? (Necessary?)

9. Production Rate Frankfurt: –Theoretical rate: 1 chamber/ week –Assumed 0.5 ch./week for next 6 chambers, then 2 chambers / 3 weeks (starting in May) → 100% of 50/60%: April 2007 100% of 100%: April 2008

10. Production Rate cont. Bucharest: –Since April 2005: average rate of 1 ch./week –Since christmas: average rate of 1.6 ch./week –Assuming: average rate of 4 ch./3 weeks (1.3) → 100% of 50/60%: Oct. 2006 100% of 100%: Feb. 2008

11. Production Rate cont. GSI –Since April 2005: average rate of 1 ch./week –Since christmas: average rate of 1.5 ch./week –Assuming: average rate of 4 ch./3 weeks (1.3) → 100% of 50/60%: July 2006 100% of 100%: Sep. 2007

12. Production Rate cont. Dubna –Since April 2005: average rate of 1 ch./week –Since christmas: average rate of 0.7 ch./week –Assuming: average rate of 1 ch./ week → 100% of 50%: July 2006 100% of 60/100%:Jan. 2007

13. Production Rate cont. Heidelberg: –Since April 2005: average rate of 0.4 ch./week –Since christmas: average rate of 0.7 ch./week –Assuming: average rate of 4 ch./6 weeks (0.7) → 100% of 50/60%: Sep. 2006 100% of 100%: Aug. 2007

14. Production rate (60% TRD) If no more money flows: –Heidelberg will have to take over some L0C1 production from Frankfurt –Dubna will delay if 60%TRD, OK if 50%TRD If we get more money: –100% of chambers (324 for 60%, 270 for 50%) will be achieved in any case without need for any changes.

15. New 75% chambers complete Milestone New milestone is required: 75% of chambers complete. Counting chambers (regardless of type): 75% achieved in May 2006 With same definition: 100%(270 chambers) achieved in Okt. 2006

17. Chamber Transport
