摘要
KM3NeT 是一个安装于地中海深海的研究基础设施。它将容纳一个中微子望远镜，由数百个联网系泊装置——探测单元或弦列组成，配备光学仪器以探测由附近中微子诱发碰撞产生的带电粒子所生成的切伦科夫辐射。与通常用于海洋学的系泊装置相比，KM3NeT 弦列的几个关键特征不同：仪器封装于透明因而无保护的玻璃球中；使用两根细的 Dyneema 绳作为承力构件；以及一根细而脆弱的骨干管沿系泊全长布置，分别用光纤与铜线传输数据与电力。此外，与地中海的 ANTARES 和贝加尔湖的 GVD 等其他中微子望远镜相比，KM3NeT 弦列更纤细，以最小化用于支撑光学传感器的材料用量。而且，在几年内部署大量弦列的速率是前所未有的。出于所有这些原因，针对 KM3NeT 弦列的布放，设计了一种定制的快速部署方法。尽管弦列长达数百米，其纤细设计使其可被压缩进一个小型可重复使用的球形发射器中，而非从水面船只将系泊重物下方部署。在降至海底后，弦列展开至全长，浮力发射器沿两根绳索滚动。本文详述了该发射器的设计、装填弦列及其水下自展开过程。
