摘要
讨论了由美国德州理工大学研制的紧凑型马克思发生器驱动的低阻抗磁绝缘传输线振荡器的研制。该项目的目标是开发一个在s波段内运行的MILO,可以提供大于1gw的射频峰值输出功率,效率高于10%。该器件设计遵循一组基本设计方程,并应用于CST Studio Suite (CST),用于颗粒单元(PIC)模拟,以模拟MILO。这些模拟结果然后通知模型的变化,以优化设备的预期性能。模拟的发展是为了考虑现实的材料特性,然后应用到设备的关键表面。此外,还包括一个电路仿真来模拟马克思发生器馈送的输入,以模拟最终的实验设置。电流结果验证了在TM01模式下,当输入信号的峰值电压为600 kV,峰值电流为58 kA时,在2.5 GHz下工作的预期射频峰值功率约为4.5 GW。仿真证实了设计应该在这些约束条件下执行。
The development of a low-impedance magnetically insulated transmission line oscillator (MILO) driven by a compact Marx generator developed by Texas Tech University is discussed. The goals of the project aim to develop a MILO operating within the S-Band that can provide an RF peak output power of greater than 1 GW with greater than 10% efficiency. The device design followed a set of base design equations that were applied to a CST Studio Suite (CST) for a Particle-in-Cell, PIC, simulation to model the MILO. These simulation results then inform changes to the model to optimize the prospective performance of the device. The simulations were developed to account for realistic material properties that were then applied to critical surfaces of the device. Additionally, a circuit simulation was included to model a Marx generator feeding the input of the MILO to simulate the eventual experimental setup. Current results verify an expected RF peak power of approximately 4.5 GW at 2.5 GHz operating in the TM01 mode when excited with an input signal that has a peak voltage of 600 kV while providing a peak current of 58 kA. The simulation confirms the design should perform within these constraints.
