为了进行偏滤器的模拟研究，在伽马10/PDX上新安装了微波干涉仪。利用偏滤器模拟实验模块（D模块）研究了在开放磁场位形下的伽马10/PDX端室偏滤器的物理特性。D模块具有带入口孔的矩形腔室。两个钨靶板呈V形安装在腔室内。为了加深对偏滤器模拟实验的理解，采用外差微波干涉仪和一维喇叭天线混频器阵列（HMA）测量了V形靶板内部的电子密度和密度分布。在H2气体注入实验中首次观察到D-模块内部的线平均电子密度分布。
Microwave interferometer has newly been installed on GAMMA 10/PDX for divertor simulation study. A divertor simulation experimental module (D-module) is used to investigate the physics of divertor in the end-cell of GAMMA 10/PDX where an open magnetic field configuration is formed. D-module has a rectangular chamber with an inlet aperture. Two tungsten target plates are mounted in V-shape inside the chamber. In order to develop understandings of divertor simulation experiments the microwave interferometer using heterodyne scheme and a 1D horn-antenna mixer array (HMA) is applied to obtain electron density and density distribution inside the V-shaped target plates. Line-averaged electron density distributions inside D-module are first observed in H 2 gas injection experiments.
