Separatrix radius measurement of field-reversed configuration plasma in FRX-L

Review of Scientific Instruments, 2004
Magnetic pickup coils and single turn flux loops are installed on the FRX-L device. The combination of the two measurements provides the excluded flux radius that approximates the separatrix radius of the field-reversed configuration (FRC) plasma. Arrays of similar probes are used to map out local magnetic field dynamics beyond both ends of the theta ...

Fluctuation characteristics of the TCV snowflake divertor measured with high speed visible imaging [PDF]

, 2018
Tangentially viewing fast camera footage of the low-field side snowflake minus divertor in TCV is analysed across a four point scan in which the proximity of the two X-points is varied systematically.

Possible influence of near SOL plasma on the H-mode power threshold

Nuclear Materials and Energy, 2017
A strong effect of divertor configuration on the threshold power for the L-H transition (PLH) was observed in recent JET experiments in the new ITER-like Wall (ILW) [1–3]. Following a series of EDGE2D-EIRENE code simulations with Be impurity and drifts a

FEATURES OF THE DEVELOPMENT OF A CIRCULAR SOLAR FLARE

Odessa Astronomical Publications, 2020
We present the results of the analysis of morphology and evolution of the circular solar flare using H-alpha images. H-alpha filtergrams were obtained with the Meudon spectroheliograph.

Heterogeneous Extractive Batch Distillation of Chloroform - Methanol – Water : Feasibility and Experiments [PDF]

, 2008
A novel heterogeneous extractive distillation process is considered for separating the azeotropic mixture chloroform – methanol in a batch rectifying column, including for the first time an experimental validation of the process.

Bifurcations of Umbilic Points and Related Principal Cycles

, 1979
The simplest patterns of qualitative changes on the configurations of lines of principal curvature} around umbilic points on surfaces whose immersions into $\mathbb R^3$ depend smoothly on a real parameter (codimension one umbilic bifurcations) are ...

Access to an ELM-suppressed X-point radiator regime in TCV snowflake minus configurations

Nuclear Materials and Energy
TCV’s operating regime with an X-point radiator (XPR) has been broadened by changing the magnetic geometry. XPRs have properties that could make them an attractive power exhaust solution for fusion reactors.

Dynamics of vortex dipoles in anisotropic Bose-Einstein condensates

, 2015
We study the motion of a vortex dipole in a Bose-Einstein condensate confined to an anisotropic trap. We focus on a system of ordinary differential equations describing the vortices' motion, which is in turn a reduced model of the Gross-Pitaevskii ...

Euler, Jacobi, and Missions to Comets and Asteroids [PDF]

, 2001
Whenever a freely spinning body is found in a complex rotational state, this means that either the body is a recent victim of an impact or a tidal interaction, or is a fragment of a recently disrupted progenitor.

Electroweak Bubble Nucleation, Nonperturbatively [PDF]

, 2000
We present a lattice method to compute bubble nucleation rates at radiatively induced first order phase transitions, in high temperature, weakly coupled field theories, nonperturbatively.
