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…
An active feedback recovery technique from disruption events induced by m=2 n=1 tearing modes in ohmically heated tokamak plasmas
P. Zanca, R. Paccagnella, C. Finotti +6
We present experimental results of magnetic feedback control on the m=2, n=1 tearing mode in RFX-mod operated as a circular ohmically heated tokamak. The feedback suppression of th…
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…
