Abstract
The DIRC, a new type of ring-imaging Cherenkov detector that images in ternally reflected Cherenkov light, is being constructed as the main h adronic particle identification component of the BABAR detector at SLA C. The device makes use of 5 meter long fused silica (colloquially cal led quartz) bars, which serve both as the Cherenkov radiators and as l ight pipes for transmitting the light to an array of photo-multiplier tubes. This paper describes a program of research and development aime d at determining whether bars that meet the stringent requirements of the DIRC can be obtained from commercial sources. The results of studi es of bulk absorption of fused silica, surface finish, radiation damag e and bulk inhomogeneities are discussed.
