TL;DR: In this paper, the evolution of a reversed-field-pinch plasma towards a self-organized single-helicity state suggests that instability problems, which have previously hindered the development of these devices, could now be overcome.

TL;DR: Improvements of plasma temperature, confinement, and pulse length, and strong mitigation of plasma-wall interaction and mode locking are reported in the modified reversed field experiment.
Journal ArticleDOI
Core transport improvement during poloidal current drive in the rfx reversed field pinch
R. Bartiromo,Piero Martin,S. Martini,T. Bolzonella,A. Canton,Paolo Innocente,Lionello Marrelli,Andrea Murari,Roberto Pasqualotto +8 more
TL;DR: In this article, the electron temperature profile is seen to peak in the plasma core, consistently with a reduction of the heat conductivity due to a substantial decrease of MHD dynamo fluctuations.
Journal ArticleDOI

TL;DR: Clean mode control (CMC) as mentioned in this paper was proposed to correct the aliasing of the sideband harmonics generated by the discrete saddle coils in real time, which leads to a smoother (i.e. more axisymmetric) boundary.
Journal ArticleDOI
Behaviour of electron density profiles and particle transport analysis in the RFX reversed field pinch
TL;DR: In this article, a detailed investigation of the form of the electron density profile during the current flat-top phase in different experimental conditions has been performed, and the results are compatible with a transport mechanism based on parallel transport along stochastic magnetic field lines in a large part of the plasma core region.
