A saturation-absorption rubidium magnetometer with multilevel optical Bloch-equation modeling for intermediate-to-high fields
Mayand Dangi, Prateek Rajan Gupta, Joseph Kasti +5
We present SASHMAG (Saturated Absorption Spectroscopy High-field MAGnetometer), an atomic sensor designed for precision magnetic-field measurements in the intermediate-to-high fiel…
Characterizing Flux-Surface Shapes in Tokamaks and Quasi-Symmetric Stellarators
M. J. Gerard, M. J. Pueschel, S. Stewart +2
Modern stellarator designs routinely attain high levels of magnetic-field quasi-symmetry through flux-surface shaping. Here, we examine different methods for characterizing stellar…
On the effect of flux-surface shaping on trapped-electron modes in quasi-helically symmetric stellarators
M. J. Gerard, M. J. Pueschel, B. Geiger +5
Using a novel optimization procedure it has been shown that the Helically Symmetric eXperiment (HSX) stellarator can be optimized for reduced trapped-electron-mode (TEM) instabilit…
Advancing technologies for high-resolution spatial and temporal measurements of macroscopic stellarator flows
A. M. Wright, D. J Den Hartog, B. Geiger +3
Stellarators, together with tokamaks, represent the two mainstream approaches to realizing fusion energy via toroidal magnetic confinement of highly ionized gases - plasmas - at ex…
