SDA meeting notes - Feb 14, 2005

Attending: Vaia, Elliott, Paul, Aimin, Tim

Action items( probably not complete...:

   1. Decide what datalogger to use for D0ILUM.  Decide
      If the time interval for reverting to Backup
      datalogger should be shortened. ( Vaia et al)

   2. Get the Feb 7-14 integrated luminosity plot rebuilt.
         (done) - Suzanne

   3. Check if Aimin's MINUIT problems are a JAS problem
      or in using Minuit.  Contact JAS people if needed.
      (Aimin, Paul)

   4. Check then make new frozen library for tables
      (Vaia, Tim)

   5. Meet with aimin later in the week to look at the
      analysis plots.

1.  Problem with derived tables and store checker.

    The weekly luminosity table stopped updating on Feb 10.
    Also, the luminosity email was not working correctly.
    Michelle looked at Tomcat on dpe11 and it looked OK
    but it was restarted anyway  and that
    seems to have fixed the problem,  Other things
    like Paul's tune fitter also needed restarting.  Jim
    Patrick suspects it was related to the restarting of the
    Linux machines on Thursday during the shutdown.

    Tuesday morning the luminosity plots that are rebuilt
    every night were fine.

2.  Tables

    There have been a number of improvements in the tables and there
    is a subpage with a number of speciality tables that will soon be
    made public.

    D0 luminosity disappeared from the Inst2 datalogger.  Vaia will
    resolve this.

    Vaia and Tim are working on a new frozen version of the code that
    makes the tables.

    It will have a fix for the bug in the MI SBD labview code that
    recently starting affecting the SBD data.  There are also changes
    that Elliott and Aimin have made.  Vaia wanted to do this in
    stages, but  tim thought it best to try to do it all at once.
    On Tuesday Vaia reported that indeed there are more changes in the
    test version of the Supertable II than expected, and they will
    take time to track down.

3. Minuit in JAS

    Aimin talked more about her problems using the JAS interface to
    Minuit.  We decided that Paul would help her report the problem
    to SLAC.

4. Analysis of RR vs Accumulator pbar bunches.

    Aimin has put her plots into the document database.  This week
    she will make the improvements suggested by various people,
    including using the mean and sigma instead of the 36 bunches.
    She will meet with Jean and anyone else who is interested on
    Wednesday or Thursday to go over her work.
