Tailoring of electron flow current in magnetically insulated transmission lines
It is desirable to optimize (minimizing both the inductance and electron flow) the magnetically insulated vacuum sections of low impedance pulsed-power drivers. The goal of low inductance is understandable from basic efficiency arguments. The goal of low electron flow results from two observations: (1) flowing electrons generally do not deliver energy to (or even reach) most loads, and thus con...

متن کاملStudies of Separation Distances in a Magnetically Driven Shock Tube with Parallel-Plate Electrodes
The separation distances between the pressure, the luminous, the ionization and the current front in a magnetically driven shock tube were investigated under discharge conditions of constant voltage and variable pressures. In order to achieve a steady-state, one-dimensional flowparallelplate electrodes and a constant voltage energy source were chosen, onventional magnetic probe and piezo-electr...
متن کاملShock-triggered formation of magnetically-dominated clouds
Aims. To understand the formation of a magnetically dominated molecular cloud out of an atomic cloud. Methods. A thermally stable warm atomic cloud is initially in static equilibrium with the surrounding hot ionised gas. A shock propagating through the hot medium interacts with the cloud. We follow the dynamical evolution of the cloud with a time-dependent axisymmetric magnetohydrodynamic code....
متن کاملCollapse of cycloidal electron flows induced by misalignments in a magnetically insulated diode
The effect of a slight misalignment in the magnetic field on a magnetically insulated diode is investigated. It is found that a slight tilt in the magnetic field, with a minute component along the dc electric field, completely destabilizes the cycloidal electron flow in the crossed-field gap. The final state consists of the classical Brillouin flow superimposed by a turbulent background, togeth...
