T-crate

• T-crate is composed by
• 12 TDR2 (this presentation)
• 2 TBS (covered by Mauro)
• 4 TPSFE (covered by Mauro)
• 1 JINF (covered by Vladimir)
• 1 TBP (this presentation)
• Mechanics
• All pieces in QM2 phase and waiting for TVT
• balcony to support cables designed and
  prototype builded
• We need to test it on the crate

TDR2

• Design frozen and finished in 2002/3
• EM (3) produced in 2002
• Tested with beam
• QM1 (7) produced and tested during 2003
• Tested with beam
• QM2 (12) produced at CSIST in Feb 2004
• Tested succesfully at CSIST
• Tested with beam (TPD and T-crate together)

All docs, test procedures, results and
reports online since Feb 2004

TBP

• TBPv2.0 designed in 2004 by VK QM2 available
• Include Lecroy bus
• JINF master Lecroy bus
• Connector to TPD
• Tested almost all connections
• AMSwire
• Power line
• Slow controltemp sensor lines not yet tested
• Should be done in Perugia soon (-gt Mauro)

xPD Mechanics

• TPD and UPD were assembled last year
• Few problems found
• Bus bars
• I-frames isolation

6
xPD Bus Bars (I)

• Inner bus bars raised 6.5 mm
• Two new peek washers needed
• At least 4 different lengths of bolts

7
xPD Bus Bars (II)

• Assembly drawings will be updated and the
  sections views will we enclosed in the drawings.
• The number of bolts used to mount bus bars will
  be reduced
• New partlist with correct length and qty of bolts

• Use copper spacers (Ni plated) only when needed
• No new peek washers
• Use shorter bolts

8
I-frames

• I frames will have a local chamfer to avoid
  short circuit? REISSUE OF DRAWINGS
• A cho-term foil will be added between the board
  and the I frame ( it will be also included on
  assembly drawing and partlist)

9
Tests in Taiwan

• TVT rescheduled, window now June 15th 2005 -
  Sep 30th 2005 (2-4 weeks before on place
  needed!)
• Hybridloads and a box to accommodate them are
  under production
• Documents still need to be written!

10
Conclusions/Outlook

• T-Crate in good shape to go for tests in summer
• Additional testhardware currently under
  production
• Manpower for tests still need to be
  specified(Daniel PG)
• We would like to take T-crate mechanics to Geneva
  to vibrate the prototype of the cable-balcony
  with some cables
• TPD see Mauros presentation
