  This report discusses a control subsystem of 40 main magnetic field correctors which is a part of the superconducting synchrotron Nuclotron Control System. The subsystem is used in static and dynamic (corrector's current depends on the magnetic field value) modes. Development of the subsystem is performed within the bounds of the Nuclotron-NICA project. Principles of digital (PSMBus/RS-485 protocol) and analog control of the correctors' power supplies, current monitoring, remote control of the subsystem via IP network, are also presented. The first results of the subsystem commissioning are given.

  The subsystem is intended for the Nuclotron extracted beam parameters measurement. Multiwire proportional chambers are used for transversal beam profiles mesurements in four points of the beam transfer line. Gas amplification values are tuned by high voltage power supplies adjustments. The extracted beam intensity is measured by means of ionization chamber, variable gain current amplifier DDPCA-300 and voltage-to-frequency converter. The data is processed by industrial PC with National Instruments DAQ modules. The client-server distributed application written in LabView environment allows operators to control hardware and obtain measurement results over TCP/IP network.
