Abstract :
We have built and successfully tested a novel particle identification detector concept, the Fast Focusing DIRC (fDIRC). The prototypeʹs concept is based on the BaBar DIRC with several important improvements: (a) much faster pixelated photon detectors based on Burle MCP-PMTs and Hamamatsu MaPMTs, (b) a focusing mirror allowing a smaller photon detector, reducing the sensitivity to backgrounds in future applications, (c) electronics capable of measuring the single photon resolution to better than σ≈100–200 ps. The fDIRC is the first RICH detector to successfully correct the chromatic error by timing.
