Description

Two-dimensional emission distribution has been measured to investigate plasma transport in the edge region of LHD with multi-channel spectrometer. Relation between the emission distribution and the magnetic field structure has been investigated with a field line tracing code. It is suggested that emissions from carbon and hydrogen have correlation in space with divertor legs or magnetic field lines with short connection lengths. It is also found that each region of emission corresponds to different connection length. (authors)
