Abstract

The paper is devoted to the IPM-2 ion source ion-optical system preparation for the plasma heating experiments with a neutral beam in the Globus-M2 spherical tokamak. Within the framework of this work, a complete renovation of the ion-optical system of the ion source was carried out, including its assembly, adjustment, and testing. To assess the quality of the work performed, measurements were made of the main electrical parameters of the high-energy beam, its energy spectrum and signals from secondary emission probes. Based on the data obtained, the beam power distribution profile and its characteristic dimensions are reconstructed, and the relative concentrations of the energy components of the beam are calculated.

Globus-M2球形托卡马克中性束注入器IPM-2源离子光学系统的改造

摘要

本文致力于为Globus-M2球形托卡马克中性束等离子体加热实验准备IPM-2离子源离子光学系统。在这项工作的框架内，对离子源的离子光学系统进行了彻底的改造，包括其组装、调整和测试。为了评估所执行工作的质量，对高能束的主要电参数、其能谱和二次发射探针的信号进行了测量。根据获得的数据，重建光束功率分布轮廓及其特征尺寸，并计算光束能量分量的相对集中度。
