We had a successful collaboration meeting a week ago that I wanted to
quickly summarize for those of you who couldn't attend. I realize the
meeting was at a time when many of us have teaching responsibilities.
This is an extremely important and interesting time in the development
of the CLAS detector. We are nearing the end of installation, well into
commissioning, and we need to start turning our efforts toward
guaranteeing good physics results. This doesn't mean ignoring hardware
issues, it means making sure the hardware is realiable and able to be
monitored so that we can trust the objectivity of our results. This
means a major effort in developing on-line monitoring tools (mostly software)
to watch over the huge array of detectors we have built. At the same
time, the level of effort for off-line software must increase to give us
an understanding of the large amount of quality data we hope to obtain
soon. Much work remains before a Data Summary Tape (DST) that anyone can
believe can be made. This is a time that users can have a key role in doing
the things we all do to make experiments a success. Be sure monitoring is
robust and that you can use it on shift! Help design testing procedures.
Contribute to software for conversion of detector raw data to physical
parameters (calibrations) or to software to find tracks and identify
particles or to guarantee a robust and stable on-line system.
I try to emphasize jobs that might be done off-site. On the other hand, the work remaining on-site cannot be ignored. Installation must continue after the September test run. An installed detector is not a working detector until it is adequately tested and debugged. Test runs with pulsers, lasers, and cosmic rays will occupy many people before the December run.
Contact one of the following people if you can contribute. I list people who are in charge of organizing the effort from different directions.
There were 4 presentations on various aspects of software on Friday followed by a lengthy general discussion. Will Brooks gave an off-line manpower assessment and a glimpse into the future with present manpower. I think we are all forced to agree that significant new effort in off-line software is required if we want to have publishable data in less than 3 years. A major theme must be larger contributions from users off-site. Dennis Weygand is a new CLAS staff member with experience leading a similar organizational task at Brookhaven. He will lead the off-line effort.
