论文摘要
基于奇偶校验空间方法，提出了一种新的检测超导射频腔中异常的方法，其目标是检测淬灭并将其与其他异常区分开。基于模型的平价空间方法依赖于分析冗余，并生成根据可测量的RF波形计算的残差信号。残差是偏离模型的敏感指标，并为不同类型的异常提供了不同的签名。这种新方法不仅有助于检测故障，而且还基于检测到的故障提供了独特的签名目录。该方法在欧洲X射线射线激光器（EUXFEL）上进行了实验验证。使用这种新方法分析了当前淬火检测系统的各种类型的异常，因为当前的淬火检测系统被错误地检测到。
A novel approach to detect anomalies in superconducting radio-frequency cavities is presented, based on the parity space method with the goal to detect quenches and distinguish them from other anomalies. The model-based parity space method relies on analytical redundancy and generates a residual signal computed from measurable RF waveforms. The residual is a sensitive indicator of deviation from the model and provides different signatures for different types of anomalies. This new method not only helps with detecting faults, but also provides a catalogue of unique signatures, based on the detected fault. The method was experimentally verified at the European X-ray Free Electron Laser (EuXFEL). Various types of anomalies incorrectly detected as quenches by the current quench detection system are analysed using this new approach.
