Abstract

The processing procedure of data of MHD diagnostics for tokamaks with circular and vertically elongated plasma cross sections is presented. The utilized processing of the signals of MHD diagnostics based on the cross-S-transform reduces the fraction of incoherent components in the signals and also provides the spatial spectrum of coherent components and their time–frequency distribution.

基于MHD诊断信号交叉相干的托卡马克等离子体扰动空间谱分析

介绍了圆形和垂直伸长等离子体截面托卡马克MHD诊断数据的处理过程。利用交叉s变换对MHD诊断信号进行处理，减少了信号中不相干分量的比例，同时提供了相干分量的空间谱及其时频分布。
