A simple high-resolution differential Cerenkov counter has been constructed and tested in beams of positive particles of 3.75 and 6 Bev/c momentum. The pi meson, K meson, and proton peaks were well separated, and had full widths at half-height of about 10/sup -3/ in DELTA BETA . The total efficiency of the counter was 63%. The K peak to K- pi valley ratio was 200 to 1 at 3.75 Bev/c and 375 to 1 at 6.0 Bev/c. The limitations of the counter for use at higher momenta are discussed briefly. (auth)
