摘要

摘要介绍了一套用于校正 Globus-M2 球形托卡马克误差场的磁线圈，误差场的出现是由于托卡马克磁系统的生产和组装不完善造成的。还介绍了用于监测锁定螺旋 MHD 模式的磁传感器。介绍了在通过中性束注入加热等离子体的放电中检测锁定模式的实验结果。发现锁定模式的出现与快速离子的损失和主等离子体的约束之间存在关联。

Effect of Locked MHD Modes on the Efficiency of Plasma Heating by the Neutral Beam Injection Method at the Globus-M2 Spherical Tokamak

A set of magnetic coils used to correct the error fields at the Globus-M2 spherical tokamak, which appear due to the imperfections of the production and assembly of the tokamak magnetic system, is described. The magnetic sensors that are used to monitor the locked helical MHD modes are also described. The results of experiments on detecting the locked modes in the discharges with plasma heating by neutral beam injection are presented. A correlation is found between the appearance of the locked modes accompanied by the loss of fast ions and the confinement of the main plasma.
