Fast electrostatic microinstability evaluation in arbitrary toroidal magnetic geometry using a variational approach
M. C. L. Morren, P. Mulholland, J. H. E. Proll +5
Small-scale turbulence originating from microinstabilities limits the energy confinement time in magnetic confinement fusion. Here we develop a semi-analytical dispersion relation…

Effect of radial pressure corrugations and profile shearing on turbulence in Fusion plasmas
Ajay C. J, M. J. Pueschel, Justin Ball +3
Microturbulence can produce stationary fine-scale radial corrugations on the plasma density and temperature gradients in magnetic confinement fusion devices. We show that these str…

Resonant theory of kinetic ballooning modes in general toroidal geometry
P. Mulholland, A. Zocco, M. C. L. Morren +4
The linear theory of the kinetic-ballooning-mode (KBM) instability is extended to capture a weakly-driven regime in general toroidal geometry where the destabilization is caused by…
