We describe an experimental setup for the measurement of polarization observables in pion production near threshold. Experiments carried out with this facility use a polarized proton beam in the Indiana University Cooler storage ring, and an internal

Analyzing powers for {rvec p}p{r_arrow}pn{pi}{sup +} were measured for the first time close to threshold at beam energies that yield maximum pion momentum fractions ({eta}{equivalent_to}p{sub c.m.}{sup max}/m{sub {pi}}c) of {eta}=0.22, 0.42, and 0.50

Analyzing powers were measured and used to quantify the observation that s-wave processes dominate near threshold. Values of Ay(θπ,φπ=0°) are presented for η values of 0.22, 0.42 and 0.50. Maximum analyzing powers AN0 are equal to −0.13, −0

The time dependence of the polarization of a stored proton beam was measured near an induced depolarizing resonance. The resonance was created by a magnetic field which oscillated along the beam axis. The distance to the resonance was varied by chang

The pp → pnπ+ reaction is one of the basic inelastic nucleon‐nucleon reactions, but it has been insufficiently explored near reaction threshold. The motivation for the experiment and the solutions chosen for the experimental difficulties are dis
