The new TORPEX in-vessel toroidal conductor for the generation of a poloidal magnetic field

TORoidal Plasma EXperiment (TORPEX) is a Simple Magnetized Torus featuring open helical magnetic field lines obtained from the superposition of a small vertical component on the main toroidal field. This work introduces the experimental setup developed to ...

(N)TM Onset by Central EC Power Deposition in FTU and TCV Tokamaks

Olivier Sauter, Basil Duval, Duccio Testa, Holger Reimerdes, Alexander Karpushov, Cristian Galperti, Doohyun Kim, Dávid Wágner, Lucia Isabel Federspiel, Jonathan Rossel

The presence in plasmas of conventional and neoclassical tearing modes is a key problem for the confinement. The investigation of their onset is still an open issue to avoid plasma degradation and possible disruptions. The destabilization of the modes by ...

Generation of Whistler-Wave Heated Discharges with Planar Resonant rf Networks

Christoph Hollenstein, Alan Howling, Philippe Frédérique Bruno Guittienne

Magnetized plasma discharges generated by a planar resonant rf network are investigated. A regime transition is observed above a magnetic field threshold, associated with rf waves propagating in the plasma and which present the characteristics of whistler ...

Nonclassical Transport and Particle-Field Coupling: from Laboratory Plasmas to the Solar Wind

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Kyle Gustafson, Alexandre Dominique Bovet

Understanding transport of thermal and suprathermal particles is a fundamental issue in laboratory, solar-terrestrial, and astrophysical plasmas. For laboratory fusion experiments, confinement of particles and energy is essential for sustaining the plasma ...

Intracorporeal anchoring and guiding system with permanent magnet force modulation

Lionel Flaction

Magnetic manipulation of objects within the body is a growing field of research since the second half of the last century. Therapeutic and diagnostic capabilities offered by such technology are extended with the clinical need to make procedures less invasi ...

Production of molecular sideband radioisotope beams at CERN-ISOLDE using a Helicon-type plasma ion source

In order to account for the increasing demand for strong molecular beams for nuclear physics experiments at ISOLDE, a new radioactive ion source concept based on an RE discharge in a magnetized plasma was developed at CERN. Experimental studies at the ISOL ...

Towards understanding edge localised mode mitigation by resonant magnetic perturbations in MAST

Wilfred Anthony Cooper

Type-I Edge Localised Modes (ELMs) have been mitigated in MAST through the application of n = 3; 4, and 6 resonant magnetic perturbations. For each toroidal mode number of the non-axisymmetric applied fields, the frequency of the ELMs has been increased si ...

Resonant features of energy and particle transport during application of resonant magnetic perturbation fields at TEXTOR and DIII-D

Holger Reimerdes

In this paper, results of a direct comparison of TEXTOR and DIII-D experiments with resonant magnetic perturbation (RMP) fields are presented. This comparison of resistive L-mode plasmas at TEXTOR with highly conductive H-mode plasmas at DIII-D is useful t ...

Observations of core toroidal rotation reversals in Alcator C-Mod ohmic L-mode plasmas

Basil Duval, Alessandro Bortolon

Direction reversals of intrinsic toroidal rotation have been observed in Alcator C-Mod ohmic L-mode plasmas following modest electron density or toroidal magnetic field ramps. The reversal process occurs in the plasma interior, inside of the q = 3/2 surfac ...
