Experiments on w-band extended interaction oscillator with pseudospark sourced post-accelerated electron beam request pdf gas 78 facebook


During its conductive phase, a pseudospark discharge is able to generate a low energy electron beam with a higher combined current density and brightness compared with electron beams formed from la gas leak any other known type of electron source. In this paper, a configuration is proposed to post-accelerate an electron beam extracted from a single-gap pseudospark discharge cavity in order to achieve high quality high energy intense electron beams. The gas 91 major advancement is that the triggering of the pseudospark discharge, the pseudospark discharge itself, and the post-accelerating of the electron beam are all driven by a single high electricity dance moms song voltage pulse. An electron beam with a beam current of ∼20 A, beam voltage of 40 kV, and duration of ∼180 ns has been generated using this structure. The beam energy can be adjusted through adjusting the amplitude of the voltage pulse and the operating voltage of the whole structure, which can be varied from 24 to 50 kV with gasco abu dhabi salary an efficient triggering method under fixed gas pressure below ∼10 Pa.

Experimental studies of the production and propagation of an electron beam from a multigap pseudospark discharge are presented. From a three-gap gas outage pseudospark, a beam up to 680 A was measured at the anode at an applied dc voltage of 23 kV. This beam can propagate downstream as far as 20 cm in a gaseous environment with no guiding magnetic field, which confirms that the transport of the electron beam was based on the neutralization of the gas pains 6 weeks pregnant space charge of the electron beam due to the ionization of the gas electricity orlando molecules by the beam itself. The beam is of very small size of 1-3 mm in diameter and is ideal to drive high frequency radiation. Higher energy electron beam pulses were generated using a 14-gap pseudospark discharge powered by a cable pulser capable of producing 120 ns duration and 170 kV voltage pulses. The beam measured had a current of up to 110 A. Interactions between the produced electricity 1800s beam and a Ka-band Cherenkov maser and a W-band backward wave oscillator slow wave structure were simulated and designed. Millimeter wave pulses were bp gas prices detected from the Cherenkov maser and backward wave oscillator beam-wave interaction experiments.

A plasma jet based on a high-current pseudo-spark discharge has been developed. A pseudo-spark gas arkansas discharge (PSD) is a high-current glow-like discharge, which is formed on the left side of the minimum of the Paschen curve. Although the discharge current exceeds several tens of kiloamperes, the discharge retains the glow mode because of the hollow cathode electricity freedom system effect. The PSD is formed with a large number of arc channels, which are usually narrow. Consequently, the PSD has a large cross section. In this gas and electric phone number study, the PSD anode has a hole with a larger diameter than that of the cathode in order to generate a plasma jet. The plasma is effectively accelerated by the electromagnetic force due to the modified shape of electrodes. The electron temperature and density of the plasma jet were measured by a double probe technique. At the discharge current of 10 kA, the temperature of the plasma jet reached approximately 1.9 eV and the density gas prices under a dollar was of the order of 1014 cm-3 at the distance of 72 mm from the anode.
