Abstract :
The results of a numerical simulation of particle loss and of the study of the protection of superconducting magnets against irradiation during beam abort and localization of loss in the UNK are presented. Using a system of local orbit distortions and movable collimators, the radiation heating of superconducting dipoles can be reduced to ~0.1 mJ/g-pulse when ~1% of the intensity is lost at the first septum of the magnetic deflector. This causes a rise in the coil temperature of not more than 0.2 K
