GlueX (VRVS) Video Conference Minutes
----------------------------------------------------------------
June 22, 2004

Present: Richard Jones, Ryan Mitchell, Zisis Papandreou

1. The design of theČ erenkov and entering it in our code was
discussed.  Ryan had received minimal information from RPI with no
dimensions.  Gary Adams reported that they had done no simulations but
had only CAD drawing.  Zisis pointed Ryan to Ravi's graphics repository
and suggested that he contact Ravi for dimensions.  We should redo the
"study of the gap" around theČ erenkov.  Ryan has begun with "toy"
simulations aiming at particle ID tests between K's and pi's etc.  It was
argued that these should advance to the HDGeant stage and for this we
need a realisticČ erenkov geometry.  In a nutshell, things are at an
early stage.

2. BCAL:  Simulations will commence in Regina within July.  Ed and Zisis
will review the list of pressing simulations and which should be done
with HDFast and which with HDGeant.

3. A discussion on BMS took place but without Dave we decided to keep it
short.  In a future meeting, Dave should present the CLAS experience and
we should pursue the make/imake discussion again.  On porting HDFast to
Mac OS X, Richard cautioned that the Absoft Compiler use would be
extensive (mcfast, qq, ...) and thus potentially a time consuming job.

4. A few issues in connection to the portal were discussed:
 1. Fixed vs. free horizontal html structure as far as browser window
    width goes.  [Zisis has made some improvements since, but a lower
    threshold of about 850 pixels remains, below which the html does not
    scale with the browser window -- a future fix perhaps.  The
    discussion continued in forum "portal bug fixes/improvement to portal
    interface"]
 2. Richard and Zisis agreed that we should not add inline images to the
    forum; a link to a web server is the way to keep it, to avoid
    bloating the forum pages. 
 3. Zisis talked briefly of the new document database that will replace
    the existing "Downloads" section for Hall D Notes and Talks.  This
    product will be released by mid July.
 4. Finally, "trawling" and Blogger philosophies were discussed for the
    portal.  Zisis is reviewing a number of technologies suggested by
    Geoffrey Fox for use in our portal.  Some collaborators have also
    been looking at client journaling programs that can use one of these
    technologies to add journal entries to the portal.  This is a niche
    application that Zisis will implement if proven not to be too big of
    a project.
That was it!
