A quasi-steady magnetic field is created by a slow capacitor discharge, and the plasma sheet current is excited by a fast capacitor discharge. The plasma current sheet thus formed is collapsed into small filamentary pinches, and they are ejected outward on the current sheet plane along the magnetic field lines. This seems to correspond to the ejection of plasma and energetic particles associated with solar flares and the neutral sheet behind the earth. The visual observation together with double probe and Rogowskii coil measurements shows that the collapse of the plasma current occurs earlier as the plasma current and the external magnetic field is increased and as the initial gas pressure is decreased, and this is explained qualitatively by the resistive tearing mode instability. The electron temperature rises abruptly at a certain time only when the current sheet collapses violently., 資料番号: SA0125482000}, pages = {210--217}, title = {太陽フレアおよびNeutral Sheetのモデル実験II}, volume = {8}, year = {1972} }
