A Controlled Precision Current Source with Active Filtering for Feeding the SP-41 Magnet of the BM@N Facility at the NICA Complex

Abstract

The current source of the IP-2500 type is intended to feed the SP-41 magnet, one of the key elements in the beamline for transporting the charged-particle beam to the experimental zone of the BM@N facility (baryonic matter at the Nuclotron) at the NICA collider complex that is created at the Joint Institute for Nuclear Research (Dubna). The inductance of the magnet is 2.3 H, and its active resistance is 0.0896 Ω. The source is used for powering the SP-41 magnet with a current of 2500 A and a relative accuracy of 10−4.
