The DIRC is a new type of Cherenkov ring imaging detector, to be used for particle identification in the BaBar detector. The basic concept of DIRC is explained and the design for its use in BaBar is described here. Beam tests have been performed using a prototype DIRC detector and the results are consistent with earlier cosmic ray tests and with Monte Carlo simulations, showing that the DIRC as designed is quite adequate for the particle identification demands of the BaBar experiment. The photon yield parameter, NO, was measured to be (143±8) /cm, neglecting attenuation in the DIRC bar, which was measured to be (4.1 ±0.7)%/meter.
