Abstract

Linear deformations of yokes and other structural elements occur in the range of 0.2–3.0 mm during the cooling of the structural elements—superconducting magnets of the NICA Collider. In order to form a closed orbit near its ideal configuration and ensure stable beam circulation, it is necessary to study the nature of the displacements of Nuclotron-type SC magnets during cooling down to operating temperatures and subsequent warming up to prove the absence of the systematic displacements of magnets. The experimental layout and design of the test bench to perform measurements of the displacements of Collider’s quadrupole magnets during cooling down from 290 to 4.5 K and subsequent warming up are discussed along with the results.
