Status of U-boards

• UDR2 / UPSFEv2 / UBPv2 / S9011AUv2 / S9011B /
  DC-DC converters
• QM2 production and testing at CSIST in Taiwan
  finished.
• December 2004. First slow control tests at
  Prevessin (Andrei, Vladimir, Alexei) using JINFv2
  with full crate at CERN were successful.
• UPD-Box and U-crate currently at Karlsruhe for
  UPD-Box integration and system tests.
• A second set of U-crate boards (later to be used
  for TVT) is ordered from Taiwan for testing and
  development at Prevessin.

Boards to be taken to Europe

• Basically all remaining U-crate boards should be
  taken to Europe.
• To CERN
• 1 UBPv2
• 3 UPSFEv2 boards
• 6 UDR2 boards
• 5 or 6 UHVG boards (one of the remaining boards
  belongs to UG)
• 1 JINFv2
• To Karlsruhe/Aachen
• 1 JINFv2 (for Aachen)

UPD-Box Assembly

• Prototype UPD-Box assembled.
• Electrical tests finished.
• Slow control is working DC/DC converters can be
  switched on or off.
• Complete system test of U-crate and UPD-Box with
  cosmics test stand.
• Further system test is foreseen in Aachen
  Connection to octagon andoperation with gas
  system. Special attention to noise performance.
• Ring lug space problems will be solved by raising
  middle bus bars with copper washer.
• Before entering TVT, customs cable tiers will be
  replaced by cable tiers ordered from
  Mike/Nichelle. Board will be cleaned.

Summary

• All QM2 boards for TRD are tested and are
  available for space-qualification tests.
• UPD-Box integration completed. Electrical tests
  ok. System tests with U-crate ongoing.
• Preliminary tests with cosmics test stand
  together by UPD-box and U-crate show no
  excessive noise.
• First JINFv2 DSP slow control software is
  available (by Andrei). S9011AUv2, UPSFEv2 and
  UHVG can be controlled and monitored.
• OK for flight module production will be given, as
  soon as system tests and space qualification
  tests have been completed. (TVT, vibration, )

All primary and secondary hardware is on
JMDC (or from ground control) Verify

OK! Switch off redundant hardware
Not OK! gtManual recovery in control center.or
if problem is known and JMDC has explicit
instructions correct problem automatically
Gas ok?
