Impedance-matched Marx generators (IMGs) are considered next generation pulsed-power drivers because of their long lifetime (> 10,000 shots), repetition rate (> 0.1-Hz), fast rise time (~ 100-ns), and high-energy-delivery efficiency (~ 90%). "TITAN" is a 14-stage IMG designed to deliver 1-TW to a 2-Ω matched load. In this paper, design, simulation, and experimental results for six stages of TITAN including its triggering system, air delivery system, and pulse shaping are presented. To achieve efficiency over 85% and maximize the capability of an IMG, synchronized triggering, reduced pre-fire rate, and pulse shaping ability are crucial. In this paper, novel engineering solutions are introduced, tested, and proven to overcome those challenges. 6-stage TITAN, powered by 102 identical bricks and 102 field-distortion-triggered gas switches, could generate ~ 600-kA and ~ 700-kV across a ~ 0.9-Ω matched load when fully charged to ± 100-kV. In these experiments, 6-stage TITAN is tested up to ± 70-kV charge voltage which delivers a peak power of 330-GW to a 1.2-Ω resistive load.
阻抗匹配型马克思发生器（IMGs）因其长寿命（>10000次脉冲）、重复频率（>0.1赫兹）、快速上升时间（约100纳秒）和高能量传输效率（约90%）而被视为下一代脉冲功率驱动器。“TITAN”是一台14级的IMG，设计用于向2Ω匹配负载输送1太瓦的功率。本文介绍了TITAN六级的设计、模拟和实验结果，包括其触发系统、空气输送系统和脉冲整形。为了实现超过85%的效率并最大化IMG的性能，同步触发、降低预燃率和脉冲整形能力至关重要。本文介绍、测试并证明了新颖的工程解决方案，以克服这些挑战。由102个相同模块和102个场畸变触发气体开关供电的6级TITAN，在完全充电至±100千伏时，可在约0.9Ω匹配负载上产生约600千安和约700千伏的电压。在这些实验中，6级TITAN在高达±70千伏的充电电压下进行测试，该电压向1.2Ω电阻负载输送330吉瓦的峰值功率。
