二维(2D)等离子体图像分析有助于研究磁约束聚变等离子体中等离子体约束的改善。我们用相位成像法建立了二维干涉仪系统，用于研究串联镜GAMA10中的二维等离子体密度分布及其涨落测量。利用该系统成功地获得了电子密度及其涨落的二维轮廓。结果表明，在伽马10中应用塞式电子回旋加热，2D等离子体密度和涨落分布明显依赖于轴向禁闭势的形成。
Two dimensional (2D) plasma image analysis is useful to study the improvement of plasma confinement in magnetically confined fusion plasmas. We have constructed a 2D interferometer system with phase imaging method for studying 2D plasma density distribution and its fluctuation measurement in the tandem mirror GAMMA 10. 2D profiles of electron density and its fluctuation have been successfully obtained by using this 2D phase imaging system. We show that 2D plasma density and fluctuation profiles clearly depends on the axial confining potential formation with application of plug electron cyclotron heating in GAMMA 10.
