[en] The installation is designed for research of interactions between hadrons and polarized protons. It contains an ethylene glycol polarized target, a system of wire-spark detectors connected on-line with an EC-1010 computer, a system of scintillation and threshold Cherenkov counters for secondary particle separation. The spectrometric abilities of the installation are provided by the magnet of the polarized target with spark chambers in its field. Now it is located in a beam of the ITEP accelerator with particle momenta up to 2 GeV/c and is used for research of polarization in elastic pion-proton scattering. 1 reference
