Abstract
Results of three-dimensional simulation of the helical-dipole magnetic field are presented. The helical dipole is the key element of the spi n rotator developed for suppressing spin resonances in circular accele rators. The influence of the spin rotator built into the magnetic stru cture of the U-70 accelerator at the Institute for High-Energy Physics (IHEP) on the dynamics of the 10-GeV proton beam is analyzed. A small -scale model of the helical magnet, which was manufactured and experim entally tested, is described.
