Abstract

The coupling impedances of individual elements of the NICA collider are simulated in order to determine, at an early stage of design, the possible limitations of the beam intensity, reveal structural elements that can be the main sources of impedances, and formulate proposals for optimizing the geometry of structural elements in order to reduce the collective effects on the beam dynamics. The simulation is conducted using the CST Studio Suite commercial software [1]. The simulation results for each structural element are stored in the form of wake potentials, which can be directly used in the HEADTAIL code simulating beam dynamics. The coupling impedances are calculated from wake potentials using the Fourier transform.

NICA对撞机结构元件的电磁建模

摘要

为了在设计的早期阶段确定束强度的可能限制，模拟了NICA对撞机各个元件的耦合阻抗，揭示了可能成为阻抗主要来源的结构元件，并提出了优化阻抗的建议。为了减少对梁动力学的共同影响，结构元件的几何形状。使用CST Studio Suite商业软件[1]进行仿真。每个结构元素的模拟结果以唤醒电势的形式存储，可以直接在模拟光束动力学的HEADTAIL代码中使用。使用傅立叶变换根据唤醒电势计算耦合阻抗。
