喜鹊是英国帝国理工学院正在建造的一种TW级发电机。该发电机基于马克思脉冲线技术，专为在高电感Z收缩负载下运行而设计。四个2.4 mV马克斯，总存储能量为336kJ，通过四个5欧姆水PFL和四个同步开关耦合到一条1.25欧姆传输线。这将在150纳秒内将超过1.5毫安的电流传输到150纳赫的负载中。最初的目标是创造合适的条件来研究由固体低温氢纤维形成的等离子体中的辐射坍塌物理。本文概述了该方案，并详细讨论了脉冲功率元件的设计思想。
MAGPIE is a TW class generator being constructed at the Imperial College in U.K. The generator, based on Marx-pulsed line technology, is specifically designed to operate with a high inductance Z-pinch load. Four 2.4 MV Marx, with a total stored energy of 336 kJ, couple through four 5 ohm water PFL and four synchronized switches to a single 1.25 ohm transfer line. This delivers over 1.5 MA into a 150 nH load in 150 ns. The initial objective is to produce the right condition to study the physics of radiative collapse in a plasma formed from a solid cryogenic hydrogen fibre. This paper outlines the programme and discusses details of the design philosophy of the pulsed power components.
