A scattering system consisting of gas target cell and surrounding vacuum chamber has been completed for studying scattering from polarized gas targets. This arrangement permits the use of thinner foil windows than would be possible if the target cell were exposed to atmospheric pressure. Optical pumping is employed to polarize the target. Scattered particles can be detected at laboratory angles of 30° to 150° on each side of the beam by two independently mounted surface barrier detectors whose positions can be controlled from outside the vacuum chamber while it is under vacuum. A description of the apparatus and technical construction data are given. Also included is a brief summary of the recent nuclear scattering experiments which utilized polarized beams and targets.
