Visit of Horst Oberlack to UVic, 24-25 September 2001
Horst is the ATLAS Liquid Argon Calorimeter Project Leader

The agenda of the meeting is appended below.
Michel Lefebvre


NOTES
*****


The following is a summary of the important points that we discussed:

- Cryostat and Cryogenics ASSO 

  The ASSO is currently scheduled for early February 2002, around the
  4th.  Horst mentioned the possibility of having a combined 2-day
  ASSO with C+C, EMB and EMEC.
  
  Michel should contact Pierre Pailler with regards to what is
  required from the EC feedthrough team for the ASSO.  Michel to look
  at the ATLAS TC web page.

  The feedthrough QA/QC document is to be updated in view of the ASSO,
  making sure the interface drawing and the description of the
  reception tests are included.

  A document summarizing the endcap feedthrough project and referring
  to other notes should be produced before the ASSO.

- Feedthrough Matters

  The procurement of pin carriers is currently the limiting factor in
  the feedthrough production.  The procurement schedule should be
  reviewed at the Cryostat and Cryogenics Steering Committee meeting.
  In particular, it is felt very important to secure Tom Muller's care
  in the procurement of the pin carriers AFTER the reception of BNL's
  contingent of pin carriers.

- ATHENA HEC/EMEC beam test software

  Currently, the EMEC/HEC technical run is expected to take place in
  March or April 2002.  Horst reports that Sepp and Sacha are
  attempting the use of DAQ-1.

  We should be prepared to accept the current EPIO format with the
  EMEC block.  Progress towards the DAQ-1 format should be followed
  closely.  In particular, if it is to be used, it is important to
  have a knowledge of the data format well before the technical run.

  Ideas regarding monitoring were discussed.  The current plan is to
  provide a PAW user interface very similar to the one in use during
  HEC beam tests, and to provide the necessary basic histograms needed
  for cell diagnostics and approximate beam location.  We are
  investigating where ATHENA should be run for monitoring, that is
  either on a dedicated (and properly maintained) linux box in the
  control room, or (default option) on the atlinux machines via a
  window from the DAQ station.  EMEC colleagues will be consulted
  regarding adequate monitoring for the EMEC quantities.

  Horst to clarify with Sepp the question of how many time slices
  can/will be read for the combined beam tests.  It was noted that
  this could affect the way pedestals are computed.

- ATHENA HEC/EMEC Tutorial
  
  A tutorial will take place Friday October 12 (last day of LAr week).
  Michel to contact a few key people to encourage them to register.
  Michel to issue a reminder to the larg email list around October
  1st, with some more info.

- Contact with EMEC Team
  
  Michel to initiate contact with the EMEC team with a view to meet
  and discuss important EMEC specific topics:
  - data format
  - cell# to geometry mapping
  - reconstruction issues (HV corrections, phi corrections, ...)
  - monitoring

  Michel to contact Laurent first.

  Needless to say that our EMEC colleagues should be encouraged to
  take over some software tasks for the combined beam tests.  It is
  felt that the ATHENA framework could possible make the job division
  easier.

- Future Participation Issues

  Horst encourages us strongly to take a piece of the action in the
  performance studies.  We should carefully think about this.

  Also, Horst would appreciate our thoughts regarding the
  commissioning phase of the LAr system (which includes the pilot
  run).  What should we do to ensure that the detector is ready for
  actual physics data taking?
