摘要

In linear plasma devices, blob-like cross-field transport is enhanced especially in detached plasmas. Formation of blob-like plasmas in the linear plasma device NAGDIS-II was observed using a fast framing camera, and the mode analysis was conducted using the emission from the plasma column. From the Fourier analysis, it was seen that plasma instability was enhanced before the ejection of blob-like plasmas from the plasma column. It was found that blob-like plasmas are generated at the peripheral region of the plasma column associated with low mode number ( m = 0 - 2) plasma instability inside the plasma column.
