STARFISH 是一系列紧凑型脉冲功率发生器，用于驱动先进的 Z 箍缩实验，用于软 X 射线生成和高密度等离子体诊断等应用，其设计和构造正在牛津大学开发。这些机器的设计基于使用许多极低阻抗分布式脉冲形成线（PFL）或离散脉冲形成网络，它们并联连接，直流充电，并同时切换到负载（可以是电线或激光预电离通道）。该发生器避免使用通常用于驱动大型 Z 箍缩实验的机器中的极高电压 Marx 发生器、液体绝缘 PFL 和磁绝缘传输线。因此，发生器比传统设计紧凑得多，并且如果使用激光预电离，则应该能够以更高的重复率运行。我们的想法是建造一系列可以日常运行的发电机，其脉冲特性可以针对特定负载进行“定制”，并且高效可靠。
The design and construction of STARFISH, a series of compact pulsed-power generators to drive advanced Z-pinch experiments, for applications such as soft X-ray generation and as a high-density plasma diagnostic, is being developed in Oxford. The design for these machines is based on the use of many very low impedance distributed pulse-forming lines (PFLs) or discrete pulse-forming networks, which are connected in parallel, dc charged, and switched simultaneously on to a load which may be a wire or laser-preionized channel. This generator avoids the use of very high voltage Marx generators, liquid-insulated PFLs, and magnetically insulated transmission lines that are usually used in machines driving large Z-pinch experiments. Consequently, the generator is far more compact than conventional designs and should be operable at much higher repetition rates if laser preionization is used. The idea is to build a series of generators that can be operated routinely on a day-to-day basis, with pulse characteristics that can be ldquotailor-maderdquo for specific loads, and be both efficient and reliable.
