Synchronous observation of filament properties using a fast camera and a hybrid probe in Heliotron J

POSTER

Abstract

A perpendicular-view gas puff imaging system and a hybrid probe (combination of a Langmuir probe array and three magnetic probe coils) have been installed in Heliotron J for synchronous measurement of the filament behaviors near the last closed flux surface (LCFS). To get the information of fast camera observation position, we have compared the poloidal velocity of turbulence and intermittent ``blob'' filaments from the data of radial-scanned ion saturation current (Is) data and fast camera data, respectively.
