The University of Massachusetts polarized target has been employed with the Brookhaven Multiparticle Spectrometer to study K-proton inelastic processes at 2.3 GeV c.m. energy. The U. Mass. "spin refrigerator" target was the first of its kind to achieve high proton polarization; it is capable of more than 80% polarization with a nonuniform magnetic field of about 11 kG and a temperature of 1.2 K. This study of strange-particle inelastic processes represents the first application of the spin-refrigerator target and is unusual among polarized-target experiments in its use of a multiparticle spectrometer for detection of complex final states. This report discusses the setting up and utilization of the polarized target at the Brookhaven MPS and the subsequent analysis of K interactions with polarized protons which yield Λπ and Σ(1385)π → Λππ . |
