大电流脉冲带状线的设计挑战
Design Challenges in High-Current Pulsed Striplines
摘要：
长基线中微子设施（LBNF）将产生世界上最强的中微子束。三个串联连接的磁喇叭将需要5 kV、300 kA、800 $μ$ s脉冲，频率为1.4 Hz，以聚焦光束。将单个电源连接到这些聚焦喇叭将需要长度超过60米的低阻抗连接。为了满足将喇叭连接到电源的挑战性要求，这种连接被设计为九导体、高电流脉冲带状线。它必须通过恶劣的辐射环境，被动冷却，并具有至少30年的使用寿命。本文讨论了机械和电气方面的考虑因素，如高压霍尔效应、夹紧接头性能和洛伦兹力缓解措施，以满足规定要求。将介绍和讨论几个原型的关键设计功能的测试和实验的结果。
英文摘要：
The Long Baseline Neutrino Facility (LBNF) will produce the worlds most intense neutrino beam. Three series connected magnetic horns will require 5 kV, 300 kA, 800 $μ$s pulses at a rate of 1.4 Hz to focus the beam. Connecting a single power supply to these focusing horns will require a low impedance connection measuring over 60 m in length. To meet the challenging requirements of connecting the horns to the power supply, this connection is engineered as a nine-conductor, high-current pulsed stripline. It must pass through a harsh radiation environment, be passively cooled, and have an operational lifetime of at least 30 years. This paper discusses mechanical and electrical considerations such as high-voltage holdoff, clamped joint performance, and Lorentz force mitigations in order to meet the specified requirements. The results of tests and experiments on several prototypes of key design features will be presented and discussed.
