Abstract

The fast ion loss detector (FILD) on the HL-3 tokamak was upgraded in the experiments of 2024 Q1. A new dual-collimator detector was designed to reduce self-shadow. The effect of the rotation angle of the detector on self-shadow was analysed in order to determine the appropriate rotation angle. By inverting the orbits of lost ions in a three-dimensional model incorporating the components of the vacuum chamber, the external-shadow of the detector was analysed, and then the appropriate position of the detector was determined. Based on the upgrade of the FILD system described above, fast ion losses induced by MHD instabilities such as fishbone and sawtooth were observed in the experiments of 2024 Q1.

HL-3托卡马克上快速离子损失探测器的升级和首次测量

在2024 Q1的实验中，对HL-3托卡马克上的快速离子损失探测器（field）进行了升级。设计了一种新型双准直检测器，以减少自影。分析了探测器旋转角度对自影的影响，以确定合适的旋转角度。通过在包含真空室组件的三维模型中反演丢失离子的轨道，分析了探测器的外阴影，并确定了探测器的合适位置。基于上述field系统的升级，在2024 Q1的实验中观察到鱼骨和锯齿等MHD不稳定性引起的快速离子损失。
