DIRC principle DIRC Detector Image Collection DIRC principle



The definitive collection of DIRC plots for use in BABAR talks can be found on the Pub Board Page of Official Plots. When in doubt please do not use DIRC detector images from any other source.
This page provides a collection of some images that may be of use to BABAR speakers.


Since the most common tool for preparation of talks appears to be PowerPoint, the images are usually provided in GIF or JPEG format. Whenever available, an eps version for inclusion in, i.e. LaTeX, is also listed. Click on the image type to download the file.

Many people have contributed to the images listed below by taking the photos or creating the drawings, too many to mention individually. So, for now, no individual credits are listed.

If you see a DIRC image that was used in the past, i.e. in the list of recent DIRC talks and posters, and do not see it on this page or if you have a nice DIRC image to add to the collection, please send e-mail to jochen@slac.stanford.edu. The approval process should typically not take more than a week.
