A spark chamber-computer system for measurement of proton polarization

Abstract A system has been developed to analyze proton polarization in the energy range 200–400 MeV. It utilizes the readout from magnetostrictive delay lines on wire spark chambers and an on-line computer. At 200 MeV, the average analyzing power, using 5 cm of carbon as scattering material, is 0.51 ±0.04.
