Abstract

A model of spherical pulsed ion diode with laser-plasma anode for generation of neutrons in nuclear fusion reaction between deuterium and tritium is proposed. Formation and acceleration of deuteron packet in the diode is analyzed taking into account adiabatic mechanism of laser-plasma expansion in the form of the Riemann shock wave and the influence of electrostatic oscillations in the region of plasma–vacuum interface. Electrodynamic and neutron characteristics of the proposed accelerating tube based on the studied diode are analyzed by using the results of computer simulation.

用于中子产生的带有激光等离子体阳极的球形离子二极管模型

摘要

提出了一种用于在氘氚核聚变反应中产生中子的带激光等离子体阳极的球形脉冲离子二极管模型。考虑到黎曼激波形式的激光-等离子体膨胀的绝热机制和等离子体-真空界面区域静电振荡的影响，分析了二极管中氘核包的形成和加速。使用计算机模拟结果分析了基于所研究二极管的加速管的电动力学和中子特性。
