Research Support for Plasma Diagnostics on Elmo Bumpy Torus. Observations of EBT Ring Geometry by Means of Diamagnetic Field Measurements Using a Compensated Ferromagnetic Resonance Magnetometer, and a Preliminary Numerical Study

摘要

A preliminary numerical study of flux penetration dynamics has been made assuming a bumpy cylinder geometry for the EBT vacuum vessel. Estimates made by this study show that the diamagnetic signal from the rings should penetrate the vacuum vessel in a time on the order of 100 mS when the plasma is changed. This penetration time appears qualitatively reasonable. (ERA citation 08:022627)
