Non-neutral plasma equilibria with weak axisymmetric magnetic perturbations
The effect of weak axisymmetric magnetic and/or electrostatic perturbations on the equilibrium of a non-neutral plasma in a Malmberg-Penning trap is analyzed. Analytical and semianalytical solutions for the potential variations inside the trap are found in a paraxial limit of the perturbations for various radial density profiles of the plasma, including the case of global thermal equilibrium. I...
متن کاملMHD Simulation of Resonant Magnetic Perturbations
Resonant magnetic perturbations (RMP) have been found effective in suppressing ELMs in the DIII-D experiment [1, 2] Simulations with the M3D code indicate that plasma rotation has an essential effect on the RMP. When rotation is below a threshold, the RMP magnetic field is amplified above the vacuum field, and acquires a helical structure. The magnetic field is stochastic in the outer part of t...
متن کاملAn upgrade of the magnetic diagnostic system of the DIII-D tokamak for non-axisymmetric measurements.
The DIII-D tokamak magnetic diagnostic system [E. J. Strait, Rev. Sci. Instrum. 77, 023502 (2006)] has been upgraded to significantly expand the measurement of the plasma response to intrinsic and applied non-axisymmetric "3D" fields. The placement and design of 101 additional sensors allow resolution of toroidal mode numbers 1 ≤ n ≤ 3, and poloidal wavelengths smaller than MARS-F, IPEC, and VM...

The hair remains an integral part of beauty since centuries in most of the cultures. And loss of hair causes a huge negative psychological impact. Thus, people have been trying to find out one or the other treatment to get rid of the baldness. They have tried a variety of treatments ranging from local application of medicines to shampoos and oral medications but none have been able to give a he...
متن کاملNon-axisymmetric instability of axisymmetric magnetic fields
Context. The MHD instabilities can generate complex field topologies even if the initial field configuration is a very simple one. Aims. We consider the stability properties of magnetic configurations containing a toroidal and an axial field. In this paper, we concentrate mainly on the behavior of non-axisymmetric perturbations in axisymmetric magnetic configurations. Methods. The stability is ...
