Abstract
The DIRC is a new type of Cherenkov imaging device that will be used f or the first time in the BABAR detector at the asymmetric B-factory, P EP-II. It is based on total internal reflection and uses long, rectang ular bars made from synthetic fused silica as Cherenkov radiator and l ight guide. The principles of the DIRC ring imaging Cherenkov techniqu e are explained and results from the prototype program are presented. Its choice for the BABAR detector particle identification system is mo tivated, followed by a discussion of the quartz radiator properties an d the detector design.
