    "abstract": "The magnetic field control subsystem of the Nuclotron - a superferric ion\nsynchrotron - is described. The bending (BM), focusing (QF) and defocusing (QD)\nmagnets are powered by three supplies. The BMs are driven by the supply of a\n6.3 kA nominal current. The QFs and QDs are connected in series and powered by\nthe 6 kA supply. An additional supply of 200 A for the QFs is used to keep the\nreqired ratio I(QF)/I(QD). The BM magnetic field shape is set by a pulse\nfunction generator which produceds a reference burst (Bo-train) with a 0.1 Gs\nresolution. A real B-train of the bending magnet field with the same (0.1 Gs)\nresolution is used for feedback loop and as reference function for QD and QF\nsupplies. The QD and QF trains are utilized for feedback loop in the QD and QF\nsupplies. The control of slow extraction system suppllies is described as well.",
