The effect of toroidicity on relaxed states at low aspect ratio
R. Paccagnella, S. Masamune, I. Predebon +1
The experimentally measured single helical states in the low aspect ratio (R/a=2) RELAX device have been compared with the predictions of a cylindrical relaxation theory and a subs…
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…
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…
Signatures of non-Markovian turbulent transport in Reversed Field Pinch plasmas
F. Sattin, R. Paccagnella, F. D'Angelo
Transport of field lines is studied for a realistic model of magnetic field configuration in a Reversed Field Pinch. It is shown that transport is anomalous, i.e., it cannot be des…
