FDIRC design for SuperB

PDF Version Also Available for Download.

Description

We describe a new design of a focusing DIRC (FDIRC) for the barrel PID at SuperB. The new FDIRC will use a new detector camera attached to the existing BaBar DIRC bar boxes. The camera's double-folded optics, made of solid fused silica, uses two mirrors, one cylindrical, and one flat. The camera's volume is 25-times smaller than the BaBar DIRC stand-off box, and its photon detectors will be 10-times faster than the BaBar DIRC PMTs, ensuring a good protection against backgrounds at SuperB, which is designed to operate at {approx}100-times higher luminosity than BaBar. The detector plane consists of a ... continued below

The detector plane consists of a matrix of H-8500 MaPMTs.
