Institute of Space and Astronautical Science (ISAS), Japan Aerospace Exploration Agency (JAXA)), Sagamihara, Kanagawa Japan, The collisionless electron drift wave instability in a plasma involving sheared magnetic-fieldaligned positive-ion flow and negative ion species has been experimentally investigated. We found that negative ions tend to stabilize the instability, which is the opposite result to a number of earlier studies on negative ion plasmas. The kinetic dispersion relation predicts that the current-driven shear-modified drift wave is excited for the positive shear range, and that the D'Angelo instability is brought about instead for the negative shear range. However, the wave observed is the current-driven shear-modified drift wave through both signs of the shear., 資料番号: AA0064958003, レポート番号: JAXA-SP-06-016}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {フロー速度シア及び負イオンによるドリフト波の変調}, volume = {JAXA-SP-06-016}, year = {2007} }
