In a series of discharges on the DIII-D tokamak, fast vertical plasma jogs are used to induce
current perturbations in the steep gradient region of the H-mode edge. These current …

Transport in the DIII-D high confinement mode (H-mode) pedestal is investigated through a
periodic edge gas puff modulation (GPM) which perturbs the deuterium density and source …

The frequency of type-I ELMs decreases as the initiation of the neutral beam injection (NBI)
heating is delayed with respect to the time when plasma current (I p) reaches flat-top in the …

A non-linear system governed by multi-spatial and multi-temporal physics scales cannot be
fully understood with a single diagnostic, as each provides only a partial view, leading to …

A new integrating model has been developed to couple tokamak edge multiscale
magnetohydrodynamic (MHD) events and transport simulations, such as edge‐localized …

The H-mode pedestal, characterized by steep gradients and reduced transport, is an
essential feature of tokamak plasmas that couples the cold Scrape-Off-Layer (SOL) to the …

Tokamaks are currently being designed and built to achieve net positive unharnessed fusion
energy, an important milestone on the path to electricity production. Experimental trends …

Recently, theoretical analysis has identified plasma microinstabilities as the primary
mechanism responsible for anomalous heat transport in tokamaks. In particular, the …
