Polar 5—an electron accelerator experiment within an aurora. 4. Measurements of the 391.4 nm light produced by an artificial electron beam in the upper atmosphere

Free electron lasers (FELs) place very stringent requirements on the quality of electron beams. Present techniques for commissioning and operating electron accelerators may not be optimized to produce the high brightness beams needed. Therefore, it is proposed to minimize the beamline errors in electron accelerator transport systems by minimizing the deviations between the experimentally measured and design transport matrices of each beamline section. The transport matrix for each section is measured using evoked responses. In addition, the transverse phase space of the beam is reconstructed by measuring the spatial distribution of the electrons at a number of different betatron phases and applying tomographic techniques developed for medical imaging.

Solid Waste Incinerator

The treatment of electron beam was tested for gaseous pollutants of volatile organiccompounds (VOCs), dioxin, and inorganic oxides (NOX and SOX). The representative VOCs of xylene and toluene were oxidized completely with electron beams using prototype hybrid system equipped with electron accelerator and MnO2 catalysts. More than 90% of dioxin in municipal solid waste incinerator gases was decomposed at a dose of 14 kGy. Nitrogen oxides and sulfur oxides in coal-fired flue gases were recovered as a fertilizer by the addition of NH3 under electron-beam irradiation.Electron beam is expected to be a promising method for treating gaseous pollutants.

Pulsed Electron Beam

The paper presents the results of the experimental investigation of the pulsed electron beam propagation propagated in a drift tube filled with oxygen. The pressure was 50, 300, and 760 Torr in the drift tube. The experiments were carried out using a TEA-500 pulsed electron accelerator (450 kV accelerating voltage; 10 kA electron beam current; 80±1 ns pulse duration to the base; up to 200 J pulse energy; and 5 cm diameter beam). The electron beam was propagated in the drift tube (40 cm long), 14 cm in diameter composed of two sections equipped with two reverse current shunts. The experiments were carried out which fixed the absorbed dose registered on the walls of the drift chamber.
