TRD Chamber Status

DESCRIPTION

The TRD status update highlights crucial developments in production activities. New leak rate measurements show promising results, with production expected to commence soon. Key materials have arrived, including a soldering machine in Frankfurt and components for the X-ray test stand. The team is set to start testing immediately. Additionally, changes in the mechanical implementation require further engineering, and collaboration with suppliers like Optiprint is ongoing to enhance mechanical precision. A schedule is in place to ensure readiness by year-end.

  1. TRD Chamber Status News: • New leak rate measurements • Production is imminent • Some material arrived • Soldering machine arrived at Frankfurt • X-Ray test stand is taking shape • Bukarest joins Production Goal: get ready by end of this year TRD Status meeting Alice week Hd Clemens Adler

  2. Leak rate New Gas system from Rainer: • ~0 intrinsic leak rate Leak Rate < 0.1 mbar* l/h (~precision limit) with greased gas connectors See how it develops with realistic configuration: 5 chambers in a row, some angular deviation... TRD Status meeting Alice week Hd Clemens Adler

  3. Soldering • Soldering machine arrived at IKF (mid August) • Where to put the solder still unresolved • Start tests as soon as possible (Monday) TRD Status meeting Alice week Hd Clemens Adler

  4. Requirements defined Mechanical impementation decided: needs engineering work: September Material ordering (Hd): September Delivery: Oktober Assembly/ TÜV: Okt./Nov. X-ray Test Stand TRD Status meeting Alice week Hd Clemens Adler

  5. Increase of HV ensures longer tube life Possible with planned Power supply X-ray test stand cont. TRD Status meeting Alice week Hd Clemens Adler

  6. New winding frame is sturdy enough, even in weight reduced version Meteor displays a loss of tension over first windings. Winding machine • Winding machine modification: scheduled beginning of Sept.  need to check TRD Status meeting Alice week Hd Clemens Adler

  7. New crane for the clean room is ordered: arrives 2nd Oct. Week Needed for moving of winding frames to tables Crane TRD Status meeting Alice week Hd Clemens Adler

  8. Arrived: Wacosit profile (frame) arrived: Side profiles warped, but OK after glueing to Al profiles Voltage divider PCBs arrived Signal cables arrived In Approach: Padplanes (slight delay, due to manufacturing confusion): finished end of next week Fischer panel: ~4 weeks from now To order: Vacuum tables Glueing tables Connectors (ROB): Minimum 15k pc. = 3930 € 60% TRD: 39k pc. = 10218 € Need add. Offers? Delay... Material Status TRD Status meeting Alice week Hd Clemens Adler

  9. Production steps were discussed with Optiprint to optimize mechanical precision where we need it. Result: Question from Optiprint 2 weeks ago: „do we need this precision?? Will bring up the price considerably.“ = some unfortunate mixup...  2 week delay Padplane TRD Status meeting Alice week Hd Clemens Adler

  10. Near Term Schedule TRD Status meeting Alice week Hd Clemens Adler
