Abstract

New stellarator experiments have been launched since the last compilation of the international stellarator database in 1995. Parameter regimes have been extended by Large Helical Device (LHD), and a variety of improved modes have been found since then. The revision of the international stellarator database has been initiated, driven by these emerging interests and by the requirements for a reactor assessment. Some provisional issues are discussed. An understanding of configurational ef fects is a prerequisite to the derivation of a unified scaling. Differences in magnetic geometry are influential in characterizing energy confinement. The results from the magnetic axis and elongation scans in LHD are high-lighted. Comparison with tokamak confinement is also addressed. The revision of the database is in progress, and this paper is an interim report.
