Spectroscopic diagnostics of superthermal electrons with high-number harmonic EC radiation in tokamak reactor plasmas

EPJ Web of Conferences, 2015
A method of spectroscopic diagnostics of the average perpendicular-to-magnetic-field momentum of the superthermal component of the electron velocity distribution (EVD), based on the high-number-harmonic electron cyclotron (EC) radiation, is suggested for

Gyrokinetic Studies of Microinstabilities in the RFP

, 2013
An analytic equilibrium, the Toroidal Bessel Function Model, is used in conjunction with the gyrokinetic code GYRO to investigate the nature of microinstabilities in a reversed field pinch (RFP) plasma.

Ideal magnetohydrodynamic simulations of unmagnetized dense plasma jet injection into a hot strongly magnetized plasma

, 2011
We present results from three-dimensional ideal magnetohydrodynamic simulations of unmagnetized dense plasma jet injection into a uniform hot strongly magnetized plasma, with the aim of providing insight into core fueling of a tokamak with parameters ...

Requirements and modelling of fast particle injection in RFX-mod tokamak plasmas [PDF]

, 2017
The planned upgrade of the RFX-mod device is a good opportunity to widen the operational space of the machine, in both RFP and tokamak configurations. Installation of a power neutral beam injector is also envisaged and a NB system compatible with RFX-mod,

Inferring the scrape-off layer heat flux width in a divertor with a low degree of axisymmetry

Nuclear Materials and Energy
Plasma facing components (PFCs) in the next generation of tokamak devices will operate in challenging environments, with heat loads predicted to exceed 10 MW/m2. The magnitude of these heat loads is set by the width of the channel, the ‘scrape-off layer’

Relation between porosity‐based and crystal‐based femtosecond laser‐induced nanogratings in oxide glasses

International Journal of Applied Glass Science, Volume 17, Issue 1, January 2026.
Abstract Femtosecond laser irradiation in glass, under controlled conditions, can induce two types of nanogratings (NG): porous nanogratings (pNG) and crystal/glass nanogratings (cNG). While most glasses exhibit only one type, binary aluminosilicate glasses have shown both types of NG.

2D continuous spectrum of shear Alfven waves in the presence of a magnetic island

, 2010
The radial structure of the continuous spectrum of shear Alfven modes is calculated in the presence of a magnetic island in tokamak plasmas. Modes with the same helicity of the magnetic island are considered in a slab model approximation.

Magneto‐Thermal Assessment of Ferrofluid Flow in Corrugated Porous Domain With Rotating Cylinder for Nuclear Systems

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
This research presents a novel approach by combining magnetohydrodynamic (MHD) flow with ohmic heating to investigate the conjugate mixed convective transport of ferrofluid in a discretely heated, smooth/wavy‐walled, square‐shaped porous compartment featuring a clockwise spinning cylindrical body positioned at various locations.

Alpha Channeling with High-field Launch of Lower Hybrid Waves

, 2015
Although lower hybrid waves are effective at driving currents in present-day tokamaks, they are expected to interact strongly with high-energy particles in extrapolating to reactors.
