摘　　要：设计了用于Z箍缩丝阵实验的重频LTD 驱动器,含6路并联模组,每组由8个0.8 MA 原型模块串联组成,全真空结构.原型模块采用全新的单路触发和电感隔离技术,触发难度和重频运行可靠性得到显著优化.利用电路模拟程序对驱动器进行了仿真计算,结果表明：在初始半径1.2cm、线质量1mg/cm 的Z箍缩负载上,驱动器的输出电流峰值可到5.2 MA,前沿91ns;负载内爆最大动能78kJ,从电容储能至负载动能的转化效率为11.7%.该驱动器预期将获得高达20%～30%的辐射能量效率,可为Z箍缩物理研究提供高效的实验平台.The design of a linear-transformer-driver(LTD)accelerator for wire-array Z-pinch experiments was presented.The accelerator comprises 6modules in parallel,and each of the module has 8series 0.8MA LTD cavities in a voltage adder configuration.A prototype cavity was built,employing a novel single-pulse-trigger method,as well as charging and trigger inductors.A full circuit modeling for the accelerator was conducted.Simulation result shows that a current pulse rising to 5.2 MA in 91ns(10%-90%)can be delivered to the wire-array load,which is 1.2cm in initial radius and 1mg in mass.The max kinetic energy of the load is 78 kJ,which is 11.7% of the electric energy stored in the capacitors.This accelerator is supposed to enable a radiation energy efficiency of 20%-30%,providing a high efficient facility for research on fast Z-pinch and technologies for rep-rately operated accelerators.
