Abstract The Ba B ar DIRC runs extremely well at design luminosities, providing excellent PID in both ring and veto modes. Machine backgrounds expected as PEP-II goes to much higher luminosities (10 34 cm 2 ·s −1 or more) in the next 5 years will require faster data acquisition electronics and further shielding of the SOB from low energy machine produced gamma rays.

A novel type of Cherenkov ring imaging particle identification system (DIRC) based on the detection of ring images produced in long, fused silica radiator bars is being used to provide hadronic particle identification in the BABAR detector at PEP-II. The DIRC concept, design, fabrication, and initial performance will be briefly described. The DIRC is now fully commissioned, and has been operating in the BABAR detector on beam line at the PEP-II B Factory since late Spring 1999.
