Summary form only given. An Inertial Electro-static Confinement Fusion (IECF) device is one of the candidates among the neutron sources, and it is possible to produce the neutrons by a compact device of simple configuration. The IECF is a concept for electrostatically confining high-energy fuel ions in a spherical potential well. It consists of two grid electrodes, radii are different and centers...
We report results of investigation of a high-current electron diode with multicapillary cordierite and glass cathodes assisted by velvet-type and ferroelectric plasma source igniters, and carbon fiber cathodes. Parameters of the plasma inside the capillary channels and in the vicinity of the cathode surface were studied during the accelerating pulse in a diode powered by a ~200 kV, ~300 ns pulse....
Summary form only given. We report results on spectroscopic research of the explosive emission plasma which is formed at the cathode surface during the operation of a S-band relativistic magnetron with microwave power of ~100 MW powered by Liner Induction Accelerator (4 kA, 300 kV, 120 ns). Plasma parameters (density, temperature, expansion velocity and uniformity) were studied with time- and space-resolved...
The aim of this work is to propose a model which can describe the plasma bulk and its interaction with the cathode using current density as input parameter. The pre-sheath is modelled through a two-temperature electrical conductivity estimation which takes into account the local state of the cathode layer. Thanks to this model, the current continuity resolution change following the plasma and material...
