摘　　要：紧凑等离子体环(CT)应用广泛,可以作为聚变驱动源和脉冲X射线源等,对CT加速过程的研究是其应用方面研究的基础.描述了CT加速的基本原理,基于整体加速模型导出数值模拟方程组,采用四阶龙格-库塔法数值求解此方程组.根据Phillips实验室MARADUER的参数和SHIVA-STAR电容器组参数,对CT在同轴加速器内的加速过程进行了数值模拟,定量地分析了影响加速效率的各种因素.计算结果表明:CT的质量越大、加速器越长,加速效率越高,但加速效率存在饱和趋势;电感和电阻越小,加速效率越高;对于一定的电容器初始储能,电容值较小时加速效率越高.There are a variety of applications for compact toroids （CT） inclding pulse x - rays source, fusion driver etc, and the research of CT acceleration is the foundation of the CT application studies. The theory of CT acceleration was described, based on Whole Acceleration Model, the numerical simulation equations were derived, while the fourth -order Runge -Kutta method was used to calculate these equations. With the parameters of MARADUER in Phillips laboratory and Shiva - Star capacitor set, the CT speedup process in a coaxial accelerator was calculated and the factors affecting acceleration efficiency were analyzed quantitatively. The simulated results show that the efficiency will be improved with the increases of CT mass and accelerator length, but a saturated trend exist, and will be lower with the increases of the resistance, inductance or capacitance for a fix initial energy stored in capacitor.
