摘要 真空传输线板-锥转角过渡是多模块汇流的Z箍缩装置经常采用的结构,在不考虑磁绝缘失效、介质损耗的前提下,采用有限差分方法分析转角过渡对功率流传输的影响。初步的计算和分析表明:随着转角的变大,由阻抗不匹配引起的反射将使传输效率有所降低;前沿较陡的快脉冲在这种结构中发生严重畸变,而低频脉冲则几乎不受影响。在板-锥过渡设计中采用小转角结构,尽量减小脉冲传输方向的变化,对保证脉冲高效传输有利。 The structure of plate-to-cone transition in vacuum transmission line is often used in the multi-modules Z-pinch drivers.This kind of transition will possibly result in an unacceptable power flow loss,particularly,when the transfer angle becomes bigger.In this paper,leaving out the invalidation of magnetically insulation and the loss in the dielectric,the finite difference method is adopted to simulate how variation of the transfer angle affects the power flow.The primary calculation and analysis show that the reflection caused by unmatched impedance will decrease the transmission efficiency with the increase of the transfer angle.The fast rise pulses will be distorted seriously in this structure,while the slow rise pulse will be hardly disturbed.It is favorable for effective pulse propagation to design the transition structure with the transfer angle small as possible.
