摘要: 实现惯性约束聚变（ICF）和高产额(high yield,HY)要求脉冲驱动电流峰值达到约60 MA，采用类似SATURN和Z装置等传统的技术途径进一步提高驱动电流，从装置造价、结构复杂性和运行可靠性等方面看都具有相当大的难度，因此，需要发展新的短脉冲大电流驱动源技术，解决快Z箍缩技术发展的瓶颈。概述了国际上快Z箍缩驱动源技术的研究现状和趋势，介绍了有代表性的ICF/HY等离子体辐射源（plasma radiation source 简称PRS）或威胁级大型X射线模拟源初步概念设计、拟采用的技术途径，如俄罗斯大电流所（HCEI）基于FLTD（fast linear transformer driver）技术的直接驱动源、美国基于FLTD的新SATURN驱动源和基于FMG（fast Marx generator）技术的快Z箍缩驱动源，提出了快Z箍缩直接驱动源需要发展的关键技术。Abstract: It is required that the peak current of high power pulsed driver for fast Z-pinch reaches 60 MA to realize inertial confine fusion（ICF）and high yield (HY). With the conventional technological methods similar to the Z or Saturn apparatus, increasing driver current further is impractical and difficult according to the cost, structure complexity and reliability of the driver, so it is necessary to develop novel fast pulsed high current driver. The present art-of-state and trends of fast Z-pinch driver are summarized in the paper, and the typical conceptual designs and technological methods on ICF/HY PRS (plasma radiation source) and destroying-level super X-ray simulators in USA and Russia are outlined, such as HCEI’s UGXX1 driver and new Saturn driver based on fast linear transformer driv
