摘要：

分析了紧凑等离子体环(CT)加速的原理，给出了加速过程的辐射磁流体力学描述。采用Lagrange方法编写了二维计算程序，计算了10mg的氩CT在同轴加速器内的加速过程，得到了加速电流和辐射功率随时间的变化曲线，给出CT等离子体内部的速度和温度等物理量的分布。

Abstract:

Acceleration mechanism of a compact toroid (CT) is analyzed in detail, and the CT speedup process is described by a set of radiation magneto-hydrodynamics equations in this paper. A two-dimensional simulation code is programmed by means of Lagrange scheme, and is utilized to calculate the speedup process of a 10mg Ar CT in a coaxial acceleration facility. The change of accelerating current and radiation power with time, the radial distribution of CT speed and plasma temperature are obtained during the speedup process.

Key words: Compact toroids, Acceleration, Radiation hydrodynamics
