Dissipation of pulsed electron beam in hydrogen and oxygen in high pressure

Research output: Contribution to journalArticle

Abstract

This paper presents results of study of dissipation processes of pulsed electron beam in the oxygen and hydrogen (300 Torr). These gases are chosen owing of their use as an operating environment at pulse plasmochemical synthesis of nanosized oxides of metals. Experimental studies are conducted on the laboratory TEU-500 electron accelerator (500 keV electron energy; 10 kA ejected electron current; 60 ns half-amplitude pulse duration; 5 pps pulse repetition rate; diameter of a bunch is 5 cm). The electron beam was injected in a drift pipe through the anode window, which is the supporting lattice (with optical transparency of 95%), and through aluminum foil with a 140 microns thickness. The pipe of drift is equipped with three shunts of the return current which are fixing a signal at the same time. The received results of researches allow to make a conclusion. It is necessary to increase length to 80 cm and diameter to 30 cm of a pipe of drift for optimum absorption of a pulse electron beam by operating gas, for obtaining high efficiency of electron accelerator of pulse plasmochemical synthesis of nanosized oxides of silicon and the titan.
