摘要
Recovery of the pressure profile is examined for the W7-AS stellarator on an equilibrium database using only simulated diagnostic information from external magnetic probes. This analysis establishes the extent of profile-relevant information contained in an extensive set of external magnetic data in isolation from measurement error, hitherto a subject of some debate. It is demonstrated that the profile can be recovered up to and including an average profile and a peaking factor. The implications for magnetic-based stellarator equilibrium reconstructions are considered.
