论文摘要
在超导加速器磁铁开发方面的各种长期存在的问题中，训练是影响磁铁性能的最古老，众所周知的问题之一。了解训练过程背后的物理学对于在新磁铁设计中的适当缓解和消除这种现象至关重要。本文讨论了在超导磁体中的定位和瞬态机械事件的定位和分类中的诊断（AE）诊断的应用，以及负责过早淬火，记忆效应以及最终训练的瞬态能量释放的表征。关于美国磁铁开发计划的目标，概述了未来AE诊断开发的预期。
Among various long-standing standing problems in superconducting accelerator magnet development, training is one of the oldest and well-known issues affecting magnet performance. Understanding physics behind the training process is crucial for proper mitigation and elimination of this phenomenon in new magnet designs. This paper discusses application of acoustic emission (AE) diagnostics to localization and classification of transient mechanical events in superconducting magnets and characterization of transient energy releases responsible for premature quenching, memory effects and, ultimately, training. Prospective of future AE diagnostics development are outlined in connection to the goals of US Magnet Development Program.
