用于托卡马克装置的中性氢密度绝对测量的激光共振荧光散射仪

AN ABSOLUTE MEASUREMENT OF THE NEUTRAL DENSITY IN HT-6B TOKAMAK PLASMA BY RESONANCE FLUORESCENCE ON Hα LINE

摘要: 本文描述了一种新的高温等离子体的珍断方法。即用激光共振荧光法测量托卡马克高温等离子体中的中性氢密度。整个测量系统用瑞利散射进行绝对定标。文章具体描述了HT_6B托卡马克装置上的共振荧光散射仪及其中性氢密度的测量结果。

Abstract: A new diagnostic method using the techniques of laser-induced fluorescence (LIF)is employed to measure the neutral density in Tokamak plasma. The diagnostic apparatus was calibrated by rayleigh scattering of laser radiation. Experimental results obtained on the HT-6B Tokamak are presented and discussed.
