The DIRC
The DIRC is a plane of 4 independent boxes each containing 12 fused silica radiator bars with a size of 4.9 m x 35 mm x 17.25 mm, which are housed in an honeycomb shell with a thin aluminum skin. Each pair of bar boxes is optically coupled to a water-filled expansion volume, known as the Optical Box (OB). The Cherenkov photons from the radiators propagate through the water-filled OB and are detected by an array of Hamamatsu H12700 multi-anode photomultiplier tubes in each OB.
Routine operation
Placeholder for actions to be taken by shift crew under routine operations.

Interlocks
Expert personnel
The individuals responsible for checking that the DIRC is ready to take data and setting its operating parameters are shown in following table. Problems with normal operation of the DIRC should be referred to those individuals and any changes to their settings must be approved by them. Additional experts may be trained by the system owner and their name and date added to this table.
