The paper proposes technique for controlled commutation of energy on a dielectric surface when affected by ultraviolet radiation, formed during electric explosion of wires. Commutation characteristic of discharge can be controlled by changing intensity of surface irradiation and number of commutation channels by changing number of exploded wires. This technique, combined with other factors, is used for formation of trailing of voltage (current) at accelerating tube of direct action accelerator IGUR-3. Exploded wires are placed inside polyethylene pipes 7 m long. With simultaneous changes of electrical field strength along the length of the pipe, steepness of rise of voltage pulse, and intensity of ultraviolet radiation, duration of the trailing edge the pulse can be set from 20 ns up to 250 ns. Speed of discharge on the pipe's surface does not depend upon its length and is, respectively, 3/spl middot/10/sub 8/...3/spl middot/10/sup 7/ m/s.

At the FOM Institute for Plasma Physics "Rijnhuizen", The Netherlands, an electrostatic high power free-electron maser is operated at various frequencies. An output power of 730 kW at 206 GHz is generated by a 7.2 A, 1.77 MeV electron beam, and 360 kW at 167 GHz is generated by a 7.0 A, 1.61 MeV electron beam. The lower output power at the latter frequency is due to relatively high losses in the present mm-wave cavity. It is shown experimentally and by simulations that, depending on the electron beam energy, the FEM can operate in single-frequency regime. So far, the pulse length was limited to some 12 /spl mu/S. Nevertheless, many aspects of generation of mm-wave power have been explored, such as the dependency on electron beam current and energy and settings of the mm-wave cavity.

To investigate the non-symmetric effects on the implosion motion and the stabilities of the burning wave in the fuel layer in a target, two-dimensional simulations are carried out by using the spherical coordinate. The phenomena are assumed to be symmetric around the polar axis. For the case in which the implosion is not spherically symmetric and the real implosion center is deviated from the spherical center, the value of radius /spl tau/ is allowable to take a negative value for a given direction. The results show that the non-symmetric implosion motion invites the increase in the local fuel temperature and density. Thus the burning fraction rather increases with the non-symmetric degree of the implosion motion of the fuel in the case of a target with a practical size for fusion.

A new microwave system for a gyro-TWT in the form of a circular waveguide with a helically grooved inner surface is proposed and studied. The corrugation radically changes the wave dispersion in the region of small axial wavenumbers: at "nearly infinite" phase velocity the group velocity of the wave is finite and constant in a broad frequency band. According to the theory, this allows significant reduction in the sensitivity of the amplifier to the axial velocity spread and an increase in its efficiency and frequency bandwidth. The helical gyro-TWT is realized for the first time experimentally. In the regime of single-frequency amplification, the gyro-TWT operating at the second cyclotron harmonic with a 200 keV/25 A electron beam having a large axial velocity spread of 30% and moving in a relatively weak magnetic field of 2.2 kG yields in the X-band, a high output power of 1 MW, a gain of 23 dB and an efficiency of 20%.

In this paper, a simple theoretical model of the launched electrons (LE) equilibrium will be presented. The model allows simpler understanding of the nature of LE. It will be shown that appearance of the LE in the magnetic insulation transmission lines (MITL) gap may be preferable from the point of view of the minimum energy principle. PIC numerical simulations were also performed to investigate conditions under which the LE may appear.

The numerical simulations of a plasma opening switch (POS) involve a lot of complex physical problems. Here the two temperature magnetohydrodynamic model (MHD) is used. The computations with such model are not so time consuming, as for the particle codes, and they give reasonable results. The effect of the Hall term in MHD equations is essential for correct physical description of the process. Another essential point is in the physically correct description of plasma-vacuum boundary, where the magnetic field detaches the plasma current carrier and passes to the load. The two stages can be separated in POS dynamics. The first one is conductivity, when plasma ports the current. It is well described by MHD equations. Second stage, the opening, can be described by MHD equation, but with the attentive analysis of applicability of such a model. The simulations were concentrated mainly on the different types of POS behaviour. Such an approach can be used for optimisation of the composite plasma configuration of POS, which had been proposed to be one of the possible ways of improvement of the POS performance.

Pulsed-power diodes have been developed at the Forschungszentrum Karlsruhe and are the objects of extensive experimental as well as numerical investigations. The electrical behavior of the diodes is substantially influenced by a charged particle flow forming a non-neutral plasma inside these devices. A detailed understanding of the fundamental time-dependent phenomena (e.g., the origin of instabilities) caused by this plasma requires the solution of the Maxwell-Lorentz equations for realistic configurations with a very accurate replica of the border of the domain, where several kinds of boundary conditions are imposed. An attractive method to attack this non-linear equations numerically is the particle-in-cell (PIC) technique. As a preliminary to use the PIC approach, the relevant diode domain has to be covered by an appropriate computational mesh. Therefore, we adopt a grid model based on boundary-fitted coordinates resulting in a quadrilateral mesh zone arrangement with regular data structure. The numerical solution of the Maxwell equations in time domain is obtained by using a finite-volume (FV) approach on a non-rectangular quadrilateral mesh in two space dimensions. A very favorable property of these modern FV schemes consists in the fact that they combine inherent robustness at steep gradients with accurate resolution. In the context of self-consistent charged particle simulation in electromagnetic fields the coupling of a high-resolution FV Maxwell solver with the PIC method is a new way of approximation.

The paper presents the results from theoretical and experimental studies of a backward wave oscillator with a resonant reflector incorporated in electromagnetic system. The reflector serves simultaneously as a short modulating gap and this provides the selection of the TM/sub 01/ operating mode among parasitic transversal modes in an extended approximately twice slow-wave structure. In course of the experiment 0.8 GW microwave power in the X-band was obtained with an efficiency of 25%. The electron beam pre-modulation and the extension of BWO transversal size allowed for increasing its efficiency in a low magnetic field. A periodically-pulsed regime for BWO operation with a 20% efficiency utilizing a DC magnet with a 0.6 T field was realized.

Carbon bisulfide as a toxic impurity is present in large amounts in the gaseous waste produced by a number of industries, specifically in the production of viscose. One of the ways to lower the carbon bisulfide content of waste gases is by treating these with pulsed electron beams. Removing from air exposed to microsecond-duration electron beams is possible with low expenditures of energy, less than the bond breaking energy of this molecule. In the present communication, we furnish results of experimental studies on the removal, by use of pulsed electron beams, of the carbon bisulphide impurity from a gas mixture simulating the composition of actual industrial wastes.
