Group Internal Notes

The BABAR DIRC Collaboration group maintains a series of internal documents kept centrally at SLAC. Paper copies can be obtained by contacting ebsec@slac.stanford.edu.

PostScript and PDF copies of most DIRC Notes are available on the web. They are password protected and you will have to enter the usual BABAR web space user name and password to access those files. If you don't know that password and think you should have access to the notes on the web, please contact ebsec@slac.stanford.edu.
