Abstract

A Fast Visible Imaging Diagnostic (FVID) system, measuring the visible light emission spectrum (400-1000 nm) from tokamak plasma, has been installed on the Aditya-U tokamak to monitor the two-dimensional dynamics of the poloidal cross section of the plasma. In this work, we present the design and installation of the FVID system on the Aditya-U tokamak. The evolution of plasma and plasma-wall interactions is described. The signature of the runaway electron beam in visible imaging and its correlation with other diagnostics is presented. The estimation of the electron cyclotron resonance layer position during pre-ionization is also discussed in this work.

Aditya-U托卡马克快速可见成像诊断的初步结果。
在Aditya-U托卡马克上安装了一套快速可见成像诊断系统(FVID),用于测量托卡马克等离子体的可见光发射光谱(400-1000 nm),以监测等离子体极向截面的二维动力学。在这项工作中,我们介绍了FVID系统在Aditya-U托卡马克上的设计和安装。描述了等离子体和等离子体壁相互作用的演变。给出了电子束失控在可见光成像中的特征及其与其他诊断的相关性。本文还讨论了预电离过程中电子回旋共振层位置的估计。
