He obtains a pion background substraction of 10**6 at a electron reconstruction probability of 30%.This has to be and can be optimized with all detectors included in the simulation. * suggested: comparison of different Endcap Imaging Cherenkov detectors<br> Klaus Föhl: [[%ATTACHURL%/vrvs2007march20basis2.pdf][vrvs2007march20basis2.pdf]] rough preview * Klaus Foehl compared the performance of the two studied solution for a Cjerenkov counter in the Forward Tagret Spectrometer, the ToP DISC DIRC and the Focussing DISC DIRC, with the proximity focussing RICH with GEM-foil readout recently proposed by Lars Schmitt. * It was agreed that he will update his basics presentation for the Genua meeting with own calculations and input from the Giessen group for their new ToP Design. * A question was: Do we need a kaon-pion-seperation power in the Target Spectrometer higher than 3.5GeV/c for real physics? * discussion * In the discussion we also agreed that we urgently need - similar to the table of momenta of particle species for different theta angles - a table of seperation power of detector species for different theta angles.Thus we can see whether we cover all particles to be detected. * In Genua we want to have time for the discussion of the three different Endcap Imaging Cherenkov detectors. * It was agreed that we ask the Muon Counter group for an update of their activities.
