Propagation of a pulsed electron beam in gas compositions of carbon-containing composite nanomaterial synthesis reagents

Abstract

The paper presents the results of comprehensive studies of the efficiency of the propagation of a pulsed electron beam through a mixture of gases: titanium tetrachloride and hydrogen, titanium tetrachloride and methane, titanium tetrachloride and oxygen. These substances are the initial reagents or products of plasma-chemical reactions of the synthesis process using pulsed electron beams. The energy distribution over the beam cross section is uniform, and the temperature decreases with distance from the geometric center. The efficiency of the process of dissipation of the energy of a pulsed electron beam during its passage through gas compositions has been studied depending on the energy of the beam electrons (350–450 keV). The studies were carried out on a test bench including a TEA-500 pulsed electron accelerator, a drift chamber, and a sectioned cut-off calorimeter with a beam charge control function. The research results are of practical importance and are the main ones in the technological processes of pulsed plasma-chemical synthesis of carbon-containing nanocomposites.
