摘要

在NICA对撞机超导磁体的冷却过程中，磁链和其他结构元件在0.2-3.0 mm范围内发生线性变形。为了形成接近理想构型的闭合轨道，保证束流循环的稳定，有必要研究核素型SC磁体在冷却至工作温度和随后的升温过程中的位移性质，以证明磁体不存在系统位移。讨论了对撞机四极磁体从290 K冷却到4.5 K以及随后的预热过程中位移测量的试验台的实验布局和设计。

Study of Displacements of Quadrupole Magnets of the NICA Collider during Cooling to Cryogenic Temperatures and Warming

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.
