چکیده

Here we report on the magnetostatic ring studies at Frankfurt University. The various effects arising by confinement of non-neutral plasmas in the longitudinal magnetic field were studied in the last 2 years. Subjects of detailed investigation were the behaviour of confined charged clouds in Gabor lenses[1] and solenoids, the consequences of a hollow density profile and of mirror charges on the cloud stability (diocotron instabilities), the transient behaviour near the Brillouin flow limit (spatial variation of the Larmor radius). The beam injection into high current magnetostatic low energy storage ring with a longitudinal magnetic guiding field is investigated by experimental test setups with two toroidal bending segments. Also the particle confinement will be tested there [2], space charge compensation and cross sectional transport due to gradient and centripetal force drifts should be studied in detail. Especially external fields used by injection may influence the confinement time and stability of the circulating beam. The experiments are planned to begin in summer 2007.

Terahertz metamaterials with semiconductor split-ring resonators for magnetostatic tunability.

We studied a metasurface constituted as a periodic array of semiconductor split-ring resonators. The resonance frequencies of the metasurface excited by normally incident light were found to be continuously tunable in the terahertz regime through an external magnetostatic field of suitable orientation. As such metasurfaces can be assembled into 3D metamaterials, the foregoing conclusion also ap...

Significant Error Propagation in the Finite Difference Solution of Non-Linear Magnetostatic Problems Utilizing Boundary Condition of the Third Kind

This paper poses two magnetostatic problems in cylindrical coordinates with different permeabilities for each region. In the first problem the boundary condition of the second kind is used while in the second one, the boundary condition of the third kind is utilized. These problems are solved using the finite element and finite difference methods. In second problem, the results of the finite di...

Study of non-linear interaction of circular laser pulse propagating through hot magnetized plasma in the presence of a planar magnetostatic wiggler

In this paper, the self-focusing property of an intense circularly polarized laser pulse in hot magnetized plasma is investigated theoretically. First, an envelope equation governing the spot-size of the laser beam for both left- and right-hand polarizations has been derived in the presence of a planar wiggler. Furthermore, non-linear dispersion relation of laser pulse is obtained by using Maxw...

Magnetic reversal in nanoscopic ferromagnetic rings

We present a theory of magnetization reversal due to thermal fluctuations in thin submicron-scale rings composed of soft magnetic materials. The magnetization in such geometries is more stable against reversal than that in thin needles and other geometries, where sharp ends or edges can initiate nucleation of a reversed state. The two-dimensional ring geometry also allows us to evaluate the eff...

Initial studies of the effects of halogenated dispersions on the amount of NICS compound ring 1- (4-fluorophenyl) -2,3-dihydro-1 H-naphtho [1 and 2-e] [1 and 3] oxazin-3-one

In the 1- (4-fluorophenyl) -2,3-dihydro-1 H-naphto- [1 and 2-e] [1 and 3] oxazine-3-n, there are 4 rings, respectively, rings from the side attached to the halogen They are named C, B, A, and D. Calculations and studies show that the amount of aromatics in the halogen-ring A in all cases has the highest number. In the B loop, the predicted aromatism level is zero, and in the ring C and D, relat...
