H-β Line in a Corona Helium Plasma: A Multi-Code Line Shape Comparison

Atoms, 2018
Many spectroscopic diagnostics are routinely used as techniques to infer the plasma parameters from line emission spectra, but their accuracy depends on the numerical model or code used for the fitting process.

Investigation of Tearing Modes on the Spherical Tokamak Globus-M2 Using the Doppler Backscattering Method

Applied Sciences, 2023
In this study, we observed magnetohydrodynamic (MHD) activity of the spherical tokamak Globus-M2 which led to a deterioration in plasma confinement, such as a transition from the H-mode to L-mode, or even disruption.
