  1. TD ROC Status TRD Status meeting 26.6.2006 GSI

  2. News • Dubna: • 16 more chambers sent to GSI, should arrive in Germany today. First transport by truck from Dubna. • Oleg will come to GSI in July to test those chambers (HV test, leak test on some, full test on 1 chamber). • 3 chambers with large leaks: working on it. • Production stopped, due to lack of materials: last transport left GSI 5 weeks ago, not arrived yet. • Bucharest: • Some panels seem to be less flat than 200um (~<250 um). Will compare with measurement protocol from production.

  3. News cont. • Frankfurt: • Production bottleneck: Testing (Step motor problems, Orbishpere problems). • Humidity in Lab approaching 60% RH: Waiting for dehumidifier. • Heidelberg: • Chamber testing backlog due to Dubna/Bucharest chambers being tested • 1 Bucharest chamber seems to have unconnected anode wire: Bucharest people will repair. • Chamber building regularly disrupted by SM production, CERN visits (with my technicians) and health problems. • Profile production disrupted, by Cooling profile production: no L-profiles produced in last 3 weeks until End of July. • Front profile production stopped by LV patchpanel production.

  4. News III • GSI: • Unconnected anode wires discovered after collimation of x-ray tube was increased. • Collecting Info from all labs. • Possibly require fine granularity for chamber testing

  5. Production Status • production rate since last status meeting increased: ~6 chambers/week (raw production rate w/o testing). • Only tested chambers: 4 chambers/week.

  6. Christian Lippman (1/2006): Garfield simulation of unconnected wires
