We have constructed a large-aperture ring-imaging Cerenkov counter, intended to identify high momentum hadrons in a high pt experiment at Fermilab (E605). To date we have performed a preliminary analysis on a small subset of our data, taken during the initial operation of our counter (April-June 1982). We have obtained ¿/K separation with good efficiency from about 60 GeV/c to 120 GeV/c in momentum under high luminosity conditions (~5 × 109 protons/second on target). Approximately 84% of all single-track events having at least one detected photon have been unambiguously identified. Cerenkov photons were detected by a multi-step avalanche chamber via the photoionization of triethylamine (TEA) vapor, and a mean number of 2.8 photons per event was detected for the highest velocity particles. Improvements in photon reconstruction are expected, especially as we refine our tracking procedures.

Abstract The operating large aperture ring-imaging Cherenkov detector from the FNAL experiment E605 is described. Cherenkov ultraviolet photons are detected with a multi-step avalanche chamber using a He/TEA gas mixture and π/K/p separation is obtained from 50 to 200 GeV/ c .

Abstract Many high-data-rate experiments in elementary particle physics suffer large dead-times due to the slow speeds with which the on-line computer can read in data from each event. To eliminate this bottle-neck, we have designed, constructed, and made extensive use in a physics experiment of a 4 megabyte memory buffer which employs ordinary dynamic RAM memory chips and which accepts all of our event data generated during a beam spill at Fermilab at a rate of 14 Mbyte per second.
