Calibration of a polarized proton target Shypit, Rickey Lee
Proton polarization of a butanal 5% H₂O-EHBA-Cr(V) polarized target have been measured by elastic scattering to an accuracy of ± 2%. The four cubic centimeter target sample, suspended in a 25 KG field, was cooled by a pumped ³He refrigerator. Left right asymmetry of scattered particles were detected by a two arm telescope, each arm consisting of a MWPC and a plastic scintillator. Separation of elastic two body events in hydrogen from non-elastic two body events in nonhydrogenous material was achieved using a coplanarity test.
