A measurement of muon fluences associated with the Fermilab Proton Center charged hyperon beam

Abstract

The Fermilab Proton Center (PC) hyperon beam was commissioned in the spring of 1980 and first used by E497 to measure charged hyperon fluxes, polarization and magnetic moments. It has subsequently been used for a number of other experiments requiring beams of charged and neutral hyperons, neutral kaons and neutrons. However, a systematic measurement of muon fluence associated with the beam particles has not been done. This note describes an attempt to do so during the recent run of E756 in the winter of 1987/88. These measurements were done parasitically to the E756 running so that the choice of targets or beam conditions was not always optimal for a systematic study. It is hoped that these measurements will be useful in the estimation of backgrounds for PC experiments as well as for the design of future hyperon beams.
