Аннотация:The structure of a magnet system developed for the planned project for a universal calorimetric detector for the UNK 3x3 TeV and an induction of 1.5 T collider at Serpukhov is presented. A version for creating a magnetic field with uniformity ~1% using a wide-aperture superconducting solenoid of diameter 5.3 m and the length 6.36 m is considered.
