Multipole Configurations with Plasma Current

Plasma Configurations

The H-1NF is uniquely equipped to study magnetic configurations because of its combination of precisely controllable power supplies, the flexible coil set and the permanently installed wire-tomography mapping system. This precision and flexibility in magnetic configuration make H-1 ideal for magnetic island studies, exploring the range of magnetohydrodynamic (MHD) instabilities appearing in H-1...

Electromagnetic Current and Multipole Decomposition

In a set of two papers, we propose to study an old-standing problem, namely the electromagnetic interaction for particles of arbitrary spin. Based on the assumption that light-cone helicity at tree level and Q = 0 should be conserved non-trivially by the electromagnetic interaction, we are able to derive all the natural electromagnetic moments for a pointlike particle of any spin. In this first...

Multipole methods for nanoantennas design: applications to Yagi-Uda configurations

Development of TESPEL Configurations for Plasma Diagnostics

A Tracer-encapsulated Solid Pellet (TESPEL) injection method has been shown to be useful for many fields of plasma diagnostics. In order to provide more flexibility for such plasma diagnostics, we are developing various types of TESPELs. Here we report a new type TESPEL with a thin shell made of poly-dichlorostyrene useful for the impurity transport study. The new multilayer TESPEL configuratio...

Comparative analysis of current and magnetic multipole graphical models

In recent year, a multipole graphical model, which is constructed by using individual MCG measurements based on the equivalent current dipole (ECD) or equivalent magnetic dipole (EMD) source model, has been developed with the aim of instead of the volume conductor model in the inverse solution of cardiac source estimation. In this paper, two graphical models known as the double magnetic dipole ...
