چکیده

We report the observation of arcing damage on diagnostic shutter during glow discharge wall conditioning in LHD. The system has no experience plasma produced by electron or ion cyclotron resonance heating neutral beam injection. arc trails were observed aluminum surface but not stainless steel although both materials exposed to with same duration. difference work functions between two may be a cause divide conditions ignition.

Spatially-resolved observation of the excitation temperature in a glow discharge plasma for atomic emission spectrometry.

A two-dimensionally imaging spectrometer system was employed to obtain the spatial distribution of the excitation temperature in a glow discharge plasma for emission analysis. A Grimm-style glow discharge excitation source, whose hollow anode had an inner diameter of 8 mm, was observed over the whole emission area. The mapping of the excitation temperature was conducted by using a two-line meth...
