Monitoring and Control System of the Test Facility for Studying the Superconducting Magnets of the Final Focusing System

NRC Kurchatov Institute–IHEP has developed superconducting quadrupole magnets for the final focusing system of heavy-ion beams of the HED@FAIR collaboration of the International Ion and Antiproton Accelerator Facility (FAIR) in Darmstadt, Germany. These quadrupoles should have the unique combination of a large superconducting coil of inner diameter of 260 mm and a high magnetic-field gradient of 37.5 T/m at a magnet operating temperature of 4.5 K. To study these magnets in various operating modes, a test facility equipped with a monitoring and control system was developed. The system provides control and monitoring of the temperature, the pressure in vessels and pipelines, the value of insulating vacuum, and the level and flow rate of liquid helium and nitrogen, 46 channels in total. All parameters of the test facility are recorded in the test archive and stored in “.xls” tables and “.tdms” files on the operator’s console.
