AMS Pre-Integration

• Pre-integration activities in the CERN AMS
  Cleanroom have been going very well. There have
  been occasional technical issues, but each has
  been quickly resolved.
• The Rotation Assembly Stand (RAS) and scaffolding
  work well and allow very good access for
  operations
• Procedures have been followed with few
  modifications and occasional re-ordering of
  steps.
• ACC, TAS, Tracker installations have been
  smooth and quicker than expected.
• The pre-integration activity will definitely make
  the final flight integration quicker with less
  technical issues

AMS Pre-Integration Potential Problems
?

• Be sure to follow Clean Room procedures. If
  youre not sure, ask!
• Current plans to glue thermal blanket mounting
  pins to the LUSS. Removal of anodized surface in
  clean room?
• Delayed pre-integration of Ram Wake Radiator
  Jigs

NOTE During the TIM presentation, Prof. Ting
directed that V. Plyaskine procure another large
screen TV (low resolution) to be mounted in the
Clean Room showing the views on the website from
the video cameras. This is so people know they
are being monitored.

AMS Pre-Integration Issues

• Schedules, schedules, schedules keep them
  updated and sent to John Heilig
• Procedures have still been coming in relatively
  late compared to when they are to be implemented.
• Keep working on those ADPs!
• Several integration action items are many weeks
  late and may affect the schedule. See items in
  red on revision 21 of the action item list.

AMS Integration Issues

• Tracker cooling prior to
  de-integration
• There has been no decision on how much Tracker
  cooling is needed nor what method will be used
  during pre-integration operations.
• This is a Tracker Group decision that MUST be
  made and implemented before the TRD/UTOF is
  installed (22-Nov).
• There is no room to connect cooling ducts to the
  light traps/vents as there was on AMS-01
• The TTCS evaporator tubing may be used with
  expendable CO2 lots of CO2.

NOTE During the TIM presentation, Prof. Ting
directed that this be discussed in a telecon with
R. Battiston on 29-Oct-07.

AMS Magnet Field Mapping _at_ CERN

• Prof. Ting officially decided the Magnet will be
  shipped to CERN as soon as the flight cryostat is
  completed. It will not be commissioned prior to
  delivery. Commissioning of the cryostat will
  take place in parallel with integration
  activities. As much time as possible must be
  left for this activity.
• Therefore, magnetic field mapping must take place
  at CERN and after the Tracker is installed with
  the VC pressurized warm.
• V. Choutko will attend the meeting at SCL on
  16-Nov to discuss the field mapping requirements.
• If possible, we need to avoid mapping with the
  LUSS in place. It will save weeks of work to
  de-integrate the LTOF and RICH Reflector cables
  from the LUSS.
• If possible, we must also try to map with Tracker
  Planes 1 5 in place this will allow cabling
  to continue and also further protects the silicon
  ladders.

Weekly Integration Telecons

• Integration telecons are held every Tuesday at 8
  AM Houston / 2 PM Culham / 3 PM CERN using
  toll-free meet-me numbers. We cover
• Action items
• Schedules
• Current integration test issues resolutions
• Read access to the CAD model ftp site is
  available at http//ams.cern.ch/AMSamsexch
• The current mailing list for integration team
  members can be found at http//ams.cern.ch/AMS/am
  sexch/docs/list_ams_integ.txt
