Hill, D.; Koehler, P.; Novey, T. B.; Yokosawa, A.; Spinka, H.; Brown, C.; Law, M. E.; Lichtenstein, C.; Pipkin, F.; Sanderson, J.; Chamberlain, O.; Shapiro, G.; Steiner, H.; Burleson, G.; Rebka, G. A.; Ehrlich, R.; Hughes, V. W.; Lu, D. C.; Mori, S.; Thompson, P. A. ; Zeller, M. E.

The authors propose to measure the polarization parameter in pp, {pi}{sup -}p, and {pi}{sup +}p scattering at incident momenta of 50, 100, and 150 GeV/c over the range 0.15 {le} -t {le} 1.5 (GeV/c){sup 2}. The apparatus consists of a polarized proton target, two spectrometer arms which determine the angles and momenta of both outgoing particles, and an on-line computer. The detectors are designed to operate at incident beam rates of up to 10{sup 8} beam particles/pulse. They anticipate an error in the polarization parameter P of .005 {le} {Delta}P {le} .01 over the range .15 {le} -t {le} .8 (GeV/c){sup 2} in 100 shifts of data taking and background studies.
