Average Projection

Relativistic classical and quantum dynamics of twisted (vortex) Dirac particles in arbitrary electric and magnetic fields is constructed. The relativistic Hamiltonian and equations of motion in the Foldy-Wouthuysen representation are derived. Methods for the extraction of an electron vortex beam with a given orbital polarization and for the manipulation of such a beam are developed. The new effect of a radiative orbital polarization of a twisted electron beam in a magnetic field resulting in a nonzero average projection of the intrinsic orbital angular momentum on the field direction is predicted.

Consistent Treatment

A self-consistent stability analysis of relativistic non-neutral cylindrical electron flows propagating along applied magnetic fields is considered within the framework of the macroscopic cold-fluid-Maxwell equations. The full influence of the equilibrium self-electric and self-magnetic fields is retained. Then the E x B drift (E being the radial electric field created by the uncompensated charge) generates a radial shear, vz(r) and v0(r). The effect of the shear in the axial velocity component, as reflected in the relative axial motion of adjacent concentric layers of beam particles, is investigated. The self-consistent treatment of the problem thus shows that the equilibrium state considered in this paper is unstable.

AbstractA novel preparation method of thin films has been successfully developed by high-density ablation plasma produced by pulsed ion-beam evaporation method. The preparation is available with extremely high deposition rate (with cm/s), without heating the substrate, in a vacuum, with good stoichiometry. As an example, the preparation of phosphoresecent SrAl2O4:Eu, Dy thin films will be shown. Furthermore, a new method has been developed of the synthesis of ultrafine nanosize powders by use of microexplosion of pulsed wire discharge. As an example, the synthesis of NiFe2O4 powders will be shown, where two wires of nickel and iron were exploded by pulsed current. In addition, we have succeeded in the preparation of tungsten thin films within via holes in LSI by use of pulsed ion beam-evaporation method. In addition to the huge power per shot, a new machine has been developed of highly repetitive, pulsed power machine for the industrial applications.

Pulsed Power Generator

AbstractWith the aim to model jets produced by conical wire arrays on the MAGPIE generator, and to strengthen the link between laboratory and astrophysical jets, we performed three-dimensional magneto-hydro-dynamic numerical simulations using the code GORGON and successfully reproduced the experiments. We found that a minimum resolution of ~100 μm is required to retrieve the unstable character of the jet. Moreover, arrays with less wires produce more unstable jets with stronger magnetic fields around them.
