For the present BABAR-Dirc, the Cherenkov angular resolution is dominated by three contributions -the chromatic error, bar thickness and pixel size. This paper discusses a prototype for a Focusing Dirc, which uses a smaller pixel size, a focusing mirror to reduce the effect of the bar thickness and precise timing in the range of 50-100ps per photon to reduce the size of the chromatic error. This paper describes two novel photon detectors which are candidates for this type of concept: Hamamatsudoi:10.2172/826537 fatcat:3hsm3ycfqve4lbpcm7t7zhi6ji
