Description
We will compare proposed Focusing DIRC (FDIRC) detector concept for the SuperB with a similar TOP detector concept intended to be used at the Belle 2.
This will include the present optics design features, mechanical designs, and electronics concepts. The comparison will also be done from point of view of expected pi/K separation as a function momentum, rate capability, types of photocathodes to be used, expected aging performance, etc.
We then discuss a possible use of the Aerogel RICH or TOF methods in the forward direction, and judge if their performance is a good match to the expected momentum range and good enough to justify the effort given the solid angle of these regions, and compare them to a dE/dx performance of drift chamber.
