Abstract: We propose research and development of an "Optical trigger" to be used for B-meson selection in an LHC fixed target experiment. The optical trigger relies on Cherenkov light detection using a fast photodetector. The device is in principle sensitive to charged particles with large impact parameter, arising from secondary vertices belonging to the B-meson chain, but blind to minimum bias events originating in a small target. A rejection factor of 50 to 100 of the unwanted minimum bias events is expected, with a good detection efficiency for B-meson-originating decays. This should permit operation of LHC fixed target experiments at the forecast high rate.
