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.

Studies of various lower hybrid wave launch scenarios for non-inductive start-up on TST-2 [PDF]

EPJ Web of Conferences
Efficient non-inductive start-up of a spherical tokamak may be achieved by using lower hybrid waves that have high current drive efficiency. On the TST-2 spherical tokamak, three lower hybrid launchers are installed at the outer-midplane, top and outer ...
