| 摘 要： | 本文在国内首次将Fabry-perot干涉仪用于托卡马克等离子体诊断。实验采用一台压电驱动式Fabry-perot干涉仪通过对Hα和Dα谱线轮廓的测量来推算等离子体的氢氘含量比,从而避免了在传统的氢氘比测量中因重复放电所引起的不准确性。

| Abstract: | The Fabry perot interferometer is applied to the spectral diagnostics of Tokamak plasma successfully. The profiles of Hα and Dα lines are recorded with a Fabry perot interferometer driven by a piezoelectric crystal,and the ratio of deuterium to hydrogen in HT 6M Tokamak plasma is deduced from the peak values of the profiles,the error for the shot-to-shot discharge is avoided. |

| Keywords: | Fabry-perot interferometer Plasma Ratio of deuterium to hydrogen |
