Characterization of off-axis fishbones

Heidbrink, W. W. Austin, M. E. Fisher, R. K.

Repetitive bursting instabilities with strong frequency chirping occur in highbeta, beam-heated plasmas with safety factor q > 1 in the DIII-D tokamak. Although the mode structures differ, in many ways, the off-axis fishbones are similar to the q = 1 fishbones first observed on the Poloidal Divertor Experiment (PDX). The modes are driven by...

Prospects of Core–edge Integrated No-ELM and Small-ELM Scenarios for Future Fusion Devices

Viezzer, Eleonora Austin, M. E. Bernert, M.

One of our grand challenges towards fusion energy is the achievement of a high-performance plasma core coupled to a boundary solution. The high confinement mode (H-mode) provides such a high-performance fusion core due to the build-up of an edge transport barrier leading to a pedestal. However, it usually features type-I edge localized modes...
