Magnets of the SPASCHARM Experiment at the U-70 Accelerator Facility

Abstract
A system of four magnets is described, which is part of the experimental installation of the SPASCHARM at the U-70 accelerator facility for the study of spin effects in hadron interactions. A unique magnet with the field of 2.4 T and the field uniformity at the level of 10–4 in the working volume of 60 cm3 serves to pump and retain polarization in a polarized proton frozen target. A special wide-aperture magnet is the central part of the spectrometer of the installation based on drift tubes. For precision guidance of the beam to the center of the target, two small-sized correcting magnets developed by the Efremov Research Institute of Electrophysical Equipment (NIIEFA) were manufactured and introduced into the installation.
