The STAR experiment

All calibration information is stored in the STAR database.  We have the following tables for BEMC calibrations:

• For the BTOW and BPRS detectors:
• St_emcCalib - this table contains absolute gain information for each channel
• St_emcPed - this table contains pedestal values for each channel
• St_emcGain - this table contains a gain correction factor vs. time for each channel (not currently used)

This database stores all BEMC trigger information such as trigger status, masks and pedestals used to obtain the high tower and patch sum information.  The database is updated online while taking data.  We have the following table formats:

These pages describe how to use the BEMC database.  There is a browser-based tool that you can use to view any and all BEMC tables available at:

Ok, after working on porting the BEMC webpages to Drupal over the past couple of days I have a list of features that I hope we can implement in our Drupal installation:

• Performance Optimizations:  I don't know if it's Drupal settings, PHP settings, or what, but this CMS is awfully slow at times.  I've set up a couple of Joomla installations at MIT that are much snappier.  This is the number one complaint I hear from other people.  It's going to be a running joke at EMC phone meetings before too long.
• Trash Bin:  What do I do with pages that I decide I don't want?  I don't see any way to trash them, so for the moment the BEMC subsystem page has a "Trash Bin" of it's own.  It sure would be nice if I could hide it, though.
• Authorship changes:  Sometimes I create pages as kocolosk that would probably be better off as staruser pages, but I don't see any way to change the authorship myself, so I've resorted on at least occasion to "trashing" the old page as best I could and then recreating a new page with a different author.  Very convoluted.
• Restricted viewership:  I would like to post analysis results in Drupal, but I can't figure out how to restrict my pages to logged in users.  At the moment I have a folder called drupal_pics in protected/spin that I put plots in.  Users are then required to type a password to see them, but again, this is something Drupal must be able to handle by itself.
