摘要

为了使数十个ma级z夹尖加速器的初始储能最小，提出了一种基于传输线编码电路模型和PSOGSA算法的智能优化方法。利用多个输入参数，可以快速确定Z-pinch加速器的四个总体参数，包括:LTD腔的连接和并联组合、堆栈- mitl系统的外半径和单片径向传输线的电气长度。通过与Z-300和Z-800概念设计结果的比较，验证了优化方法的正确性。利用这种智能优化方法，研究了影响大电流Z-pinch加速器初始能量存储的因素，如工作电场、堆- mitl系统直径和LTD腔内径。提出了设计相对低成本、高效的基于有限电路的加速器的建议。

Intelligent Optimization of Parameters for Tens of MA-Class Z-Pinch Accelerators

In order to minimize the initial energy storage of tens of MA-class Z-pinch accelerators, an intelligent optimization method was developed based on the transmission line code circuit model and PSOGSA algorithm. Using several input parameters, the four overall parameters of the Z-pinch accelerator could be fast determined, including the connection and parallel combination of LTD cavities, the outer radius of the stack-MITL system, and electrical length of monolithic radial transmission lines. The optimization method has been verified by comparing the results with the Z-300 and Z-800 conceptual designs. By means of this intelligent optimization, some factors that affect the initial energy storage on high-current Z-pinch accelerators have been investigated, such as the operating electrical fields, the diameter of the stack-MITL system, and the inner diameter of the LTD cavity. The suggestions for designing relatively low-cost, efficient LTD-based accelerators have been proposed.

期刊介绍： Laser and Particle Beams is an international journal which deals with basic physics issues of intense laser and particle beams, and the interaction of these beams with matter. Research on pulse power technology associated with beam generation is also of strong interest. Subjects covered include the physics of high energy densities; non-LTE phenomena; hot dense matter and related atomic, plasma and hydrodynamic physics and astrophysics; intense sources of coherent radiation; high current particle accelerators; beam-wave interaction; and pulsed power technology.
