Our recent Nuclear Fusion journal paper on the modelling of ASDEX Upgrade tokamak plasmas

View from the ASDEX Upgrade Control Room.

Our journal article entitled “Shear Alfvén wave continuum spectrum with bifurcated helical core equilibria” has been published in the peer-reviewed Nuclear Fusion journal. Jointly published by IAEA and IOP Publishing, Nuclear Fusion is one of the renowned journals specializing in fusion plasmas.

The paper reports on the first modelling results aimed at understanding low-frequency Alfvén eigenmodes called beta induced Alfvén eigenmodes (BAEs) observed during monster sawtooth crashes in ASDEX Upgrade tokamak plasmas and their comparison with the experimental observations.

Our new journal paper in Nuclear Fusion

Our journal article entitled “Modelling of beam-driven Alfvén modes in TJ-II plasmas” has been accepted for publication in Nuclear Fusion. Nuclear Fusion is one of the renowned journals in our field.

The paper reports on our modelling results aimed at understanding a certain type of energetic-particle-driven instabilities called Alfvén modes in TJ-II stellarator plasmas and their comparisons with experimental results. In particular, we have modelled Alfvén eigenmodes in TJ-II discharges with a dynamically changing magnetic configuration when both steady and chirping modes are observed. The modelled mode frequencies and radial locations are found to be consistent with the experimental findings. We also have drawn important conclusions on the properties of the energetic particles that are resonant with the modes.
