Relaxation models for Single Helical reversed field pinch plasmas at low aspect ratio
R. Paccagnella, S. Masamune, A. Sanpei
A recent study [1] about the scaling with the aspect ratio (i.e. the ratio between the major and minor radius of the torus) of the dominant mode in Single Helical (SH) Reverse Fiel…
From Single Helical relaxed states to helical equilibria
Roberto Paccagnella
This paper analyzes the relationship between the Single Helical relaxed states studied in R. Paccagnella, Phys. of Plasmas 23 (2016) 092512 and the so called 'helical ohmic equilib…
Coherent transport structures in magnetized plasmas II: Numerical results
G. Di Giannatale, M. V. Falessi, D. Grasso +2
In a pair of linked articles (called Article I and II respectively) we apply the concept of Lagrangian Coherent Structures borrowed from the study of Dynamical Systems to magnetic…
Coherent transport structures in magnetized plasmas, I : Theory
G. Di Giannatale, M. V. Falessi, D. Grasso +2
In a pair of linked articles (called Article I and II respectively) we apply the concept of Lagrangian Coherent Structures (LCSs) borrowed from the study of Dynamical Systems to ma…
Aspect ratio scaling of the Single Helical states in the Reversed Field Pinch plasmas
Roberto Paccagnella
In this paper a new idea is presented which is able to predict the scaling law with the aspect ratio for the toroidal mode number of the so called Single Helicity states in Reverse…
Relaxation models for Single Helical Reversed Field Pinch plasmas
Roberto Paccagnella
In this paper a relaxation theory, proposed several years ago for plasmas where a single dominant mode is present, is revisited. The solutions of the related eigenvalue problem are…
Magnetic axis safety factor of finite spheromaks and transition from spheromaks to toroidal magnetic bubbles
Paul M. Bellan, Roberto Paccagnella
The value of the safety factor on the magnetic axis of a finite-beta spheromak is shown to be a function of beta in contrast to what was used in P. M. Bellan, Phys. Plasmas 9, 3050…
