摘要

本文介绍了脉冲电子束在四氯化钛与氢、四氯化钛与甲烷、四氯化钛与氧等混合气体中传播效率的综合研究结果。这些物质是脉冲电子束合成过程中等离子体化学反应的初始试剂或产物。光束截面上的能量分布是均匀的,温度随距离几何中心的远近而降低。利用脉冲电子束的电子能量(350 ~ 450 keV),研究了脉冲电子束通过气体组分时能量耗散过程的效率。研究在TEA-500脉冲电子加速器、漂移室和带束流电荷控制功能的分段截止量热计的实验台上进行。这些研究成果是脉冲等离子体化学合成含碳纳米复合材料工艺过程中的主要研究成果,具有重要的实际意义。

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