摘要: 为有效解决驱动粒子反应需要的强电磁脉冲功率问题，在压电陶瓷堆脉冲功率源基础上研究了一种新型的基于氢等离子体加载和波粒共振机制的脉冲功率同步放大技术，其放大机理为：一是氢分子成键轨道比反键轨道能量低，在电离过程中会释放内能促进脉冲功率驱动的电离过程高效发生；二是氢原子电离后，电磁场与电离后形成的电子发生波粒共振，电子能量被同步转换为电磁场能量。波粒共振放大后获得更强的电磁脉冲能量，其作用到螺旋电极上可形成球形电磁场，并具有极高的加速梯度，可对氢原子高效电离后产生的大量质子进行近距加速。本文通过实验测试和仿真分析对上述理论进行了有效证明，该项研究有望为强电磁脉冲驱动的小型化、低成本质子发生器奠定基础。Abstract: In order to effectively solve the problem of strong electromagnetic pulse power required to drive particle reactions, a new pulse power synchronous amplification technology based on hydrogen plasma loading and wave-particle resonance mechanism is studied on the basis of piezoelectric ceramic stack pulse source. The amplification mechanism is as follows: first, the energy of hydrogen molecule bonding orbitals is lower than that of antibonding orbitals, and internal energy will be released during the ionization process to promote the efficient occurrence of the ionization process driven by pulse power; Second, after the ionization of hydrogen atoms, the electromagnetic field and electrons undergo wave-particle resonance, and the electron energy is synchronously converted into electromagnetic field energy. After the amplification of wave-particle resonance, a stronger electromagnetic pulse is obtained, which can form a spherical electromagnetic field when applied to the spiral electrode, and has an extremely high acceleration gradient, which can accelerate a large number of protons produced after efficient ionization of hydrogen atoms. In this paper, the above theory is effectively proved through experimental tests and simulation analysis, and this research is expected to lay a foundation for a miniaturized and low-cost proton generator driven by strong electromagnetic pulses.
