Measurement of Zonal Flows in a Tokamak Using Langmuir Probe Array

【摘要】 <正> Zonal flows have been measured with several novel Langmuir probe array on theHT-7 tokamak since 2002.The forked probe and its improved generation,the farmer forked probewere designed based on the original idea of the Reynolds stress triple tips array.In order tomeasure the radial shearing rate of zonal flows,the pyramid probe was also designed.This paperaddresses the technical aspects regarding this new application.Since the zonal flows dynamicsis now widely believed crucial to plasma confinement physics,an important application field ofLangmuir probe was opened up.更多还原
