Institute of Space and Astronautical Science (ISAS), Japan Aerospace Exploration Agency (JAXA)), Sagamihara, Kanagawa Japan, High-density, helicon-plasma experiment using a large-volume (73.8 cm in diameter and 486 cm in axial length) helicon-plasma device at ISAS/JAXA is described. In certain applications, such as, plasma processing and plasma thrusters, a large-diameter plasma with short length is desirable in order to reduce the power requirement for plasma production. It is demonstrated using the ISAS/JAXA helicon-plasma device that a reasonably good plasma production efficiency can be achieved even for the helicon-plasma with ca. 80 cm length. The Ar plasma density can exceed 10(exp 12)cm(exp 3) with moderate rf input power of ca.700 W (at 7 MHz).Ongoing experiments to simulate space-plasma phenomena are also briefly described. In these experiments,full device length is normally utilized., 資料番号: AA0064958004, 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 = {宇宙研における高密度ヘリコンプラズマ実験}, volume = {JAXA-SP-06-016}, year = {2007} }
