论文摘要
长基线中微子设施（LBNF）将产生世界上最激烈的中微子束。三个系列连接的磁角将需要5 kV，300 ka，800 $μ$ s脉冲，以1.4 Hz的速度将光束聚焦。将单个电源连接到这些聚焦的角将需要低阻抗连接的长度超过60 m。为了满足将号角连接到电源的挑战性要求，该连接被设计为九个导管，高电流的脉冲条线。它必须经过严格的辐射环境，被动冷却，并且运营寿命至少为30年。本文讨论了机械和电气考虑因素，例如高压持有，夹紧的关节性能以及洛伦兹力量缓解，以满足指定的要求。将提出和讨论有关关键设计特征的几种原型的测试和实验的结果。
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.
