Abstract
As part of the NICA (Nuclotron-based Ion Collider fAcility) and FAIR (Facility for Antiproton and Ion Research, Darmstadt, Germany) projects, superconducting magnets are being manufactured and tested at the V. I. Veksler and A. M. Baldin Laboratory of High Energy Physics (VBLHEP) of the Joint Institute for Nuclear Research (JINR). The structure of the NICA Collider includes 290 superconducting dipole, quadrupole, and correction magnets [1]. An energy evacuation system is used to protect magnets from damage while exiting the superconducting state. This system underwent necessary upgrade to expand the inductance range of the tested magnets to 210 mH Circuit design solutions for electronic control units were developed. Simulation and successful testing of new electronic modules were carried out. These modules were put into operation as elements of the existing cryogenic test bench for superconducting magnets. This paper describes the operating principle of the energy evacuation system and its constituent components, as well as the results of its operation during the testing of superconducting magnets for the NICA and FAIR accelerator complexes.
