The Levitated Dipole Experiment (LDX) is used to study hightemperature plasma confined by the magnetic field produced by a high-current superconducting ring. Multiple-frequency ECRH heats and sustains plasma discharges for long, quasi-steady periods, and conditions of high plasma beta are reached by adjusting the rate of neutral fueling. When the superconducting ring is levitated by attraction ...

The ubiquity of zonal flows in toroidal plasma is now well recognized (see [1] for review on zonal flow theory and a special March issue of Plasma Physics and Controlled Nuclear Fusion 87 (2006) for the latest experimental papers). Two main branches of zonal flows have been identified. Both have zero poloidal and toroidal mode numbers, m = n = 0. One of them is a zero-frequency, finitebandwidth...

We describe the first electro-optical absolute measurements of electromagnetic pulses (EMPs) generated by laser-plasma interaction in nanosecond regime. Laser intensities are inertial-confinement-fusion (ICF) relevant and wavelength is 1054 nm. These are the first direct EMP amplitude measurements with the detector rather close and in direct view of the plasma. A maximum field of 261 kV/m was m...

Energy confinement data of large fusion devices are analyzed in terms of reduced variables which consist of certain combinations of the machine variables. The goal is to predict the single variable behaviour from a data set with entries which differ in more than one variable setting from each other. Bayesian neural networks are used to model the hyper-surface evolving for the energy confinement...

Temporally and spatially resolved measurements of carbon and boron impurity density are obtained in the reversed field pinch (RFP) for the first time. It is observed that, unlike in tokamaks and stellarators, the RFP does not exhibit a centrally peaked impurity profile in either standard plasmas where field lines have some degree of stochasticity, or improved confinement discharges where there ...

The interaction dynamics of signaling complexes is emerging as a key determinant that regulates the specificity of cellular responses. We present a combined experimental and computational study that quantifies the consequences of plasma membrane microcompartmentalization for the dynamics of type I interferon receptor complexes. By using long-term dual-color quantum dot (QD) tracking, we found t...

First results of 3D kinetic simulations of rotating magnetic field (RMF) current drive in fieldreversed configuration (FRC) are presented. Self-consistent hybrid simulations have been performed using the HYM code for evenand odd-parity RMF and different FRC parameters. Simulations show that the RMF pushes the plasma radially inward, resulting in a reduced plasma density outside separatrix. Lowe...

This overview describes the confinement and structure of two-dimensional plasma crystals. Phonons and Mach cones in monolayer systems can be used for diagnostic purposes. Three-dimensional plasma crystals are found as multilayer systems or as Yukawa balls. The differences between Coulomb and Yukawa balls are described by means of a simple model. Optical diagnostic methods for studying dynamical...

Throughout this brief note all groups are assumed to be abelian p-primary, written additively as is customary when regarding the group structure. Since we shall deal exclusively only with p-torsion abelian groups, for some arbitrary but a fixed prime p, there should be no confusion in future removing the phrase ”is an abelian p-group”. Concerning the terminology, under the term a separable grou...
