Plasma rotation and diamagnetic drift effects on the resistive wall modes in the negative triangularity tokamaks

Nuclear Fusion
It was found previously that the negative triangularity (NT) configuration is more MHD-unstable for low n modes than the positive triangularity (PT) case, although the situation is reversed for intermediate n modes and the NT configuration becomes more ...

Nonlocal effects in negative triangularity TCV plasmas [PDF]

Plasma Physics and Controlled Fusion, 2021
Abstract Global gradient driven gyrokinetic simulations performed with the Gyrokinetic Electromagnetic Numerical Experiment (GENE) code are used to investigate Tokamak à configuration variable (TCV) plasmas with negative triangularity. Considering limited L-mode plasmas, the numerical results are able to reproduce

Zonal flow screening in negative triangularity tokamaks

Nuclear Fusion, 2022
Abstract This paper presents a comparative study of zonal flow screening in positive and negative triangularity tokamaks. Neoclassical screening sets the strength of zonal flow shear for fixed drive and damping. Orbit calculations show that the radial excursions of trapped particles are reduced in negative triangularity tokamaks, as ...

SIMULATION OF NEUTRAL BEAM INJECTION IN POSITIVE AND NEGATIVE TRIANGULARITY TOKAMAKS

Anales (Asociación Física Argentina), 2023
In this paper the dynamics of high energy charged particles in negative and positive triangularity tokamaks is studied through the simulation of a neutral beam injection on analytical MHD equilibria using the exact orbit code FOCUS.

Effect of negative triangularity on the bulk ions co-current rotation caused by the ion orbit loss at the edge of the tokamak plasmas

Nuclear Fusion, 2022
The ion orbit loss (IOL) can drive the bulk ions co-current rotation at the edge of the tokamak plasmas. The effect of triangularity on the IOL is investigated by using an analytical tokamak equilibrium model for the shaped plasmas.

Quantum Inozemtsev model, quasi-exact solvability and N-fold supersymmetry [PDF]

, 2001
Inozemtsev models are classically integrable multi-particle dynamical systems related to Calogero-Moser models. Because of the additional q^6 (rational models) or sin^2(2q) (trigonometric models) potentials, their quantum versions are not exactly ...

Hopf algebras and Markov chains: Two examples and a theory [PDF]

, 2013
The operation of squaring (coproduct followed by product) in a combinatorial Hopf algebra is shown to induce a Markov chain in natural bases. Chains constructed in this way include widely studied methods of card shuffling, a natural "rock-breaking ...
