TRD ROC Status Clemens Adler

1
TRD ROC Status

• TRD Meeting
• 30.3.07

2
Glue Quality Control

• Quality control at Huntsman established (thanks
  to H. Risch, GSI)
• Electrical and mechanical parameters are measured
  
• -gt We accept (or not) the batch.
• Procedure in place for the last batch of AW106
  and AW116 (all Parameters were OK)
• GSI will do some own tests for comparison
• Do we want QC procedure for old glue? (Pro
  we know what we used so far, Con we know
  what we used so far, Money)

Padplane Production

• Papdlane soldering moved from Frankfurt to TU
  Darmstadt (H.Oeschler)
• Production running since February
• 5 people (Anton Przybyla et al.)
• 100 paplanes done
• Some problems with test device (solved)

4
Radiator grounding

• Radiators are grounded with Scotch copper
  (conductive) tape to L-profiles
• Christian discovered decreasing conductivity with
  time (leading to periodic discharges -gt HV
  instabilities)
• Lesson Conductive copper tape (Scotch3M) is not
  suited for long term grounding (used in other
  places?!?)
• Solution Silver epoxy. (procedure needs to be
  defined)

Production planning cont.

• Scenario 1
• Dubna takes over 22 chambers
• Bucharest takes 22 chambers (130 ch. total) ?
• Heidelberg works twice as fast
• GSI, Frankfurt keep the rate
• -gt ROC production finished 8/2008
• Question
• Dubna L3C1 only, or L3C1L2C1 (mixture)

• Scenario 2
• ???
