Abstract

Reliability is one of the most critical metrics for accelerator operation, especially in user facilities. To reduce costly facility downtime and provide an operational environment where system performance can be reliably predicted in support of scientific studies, we are developing a model-driven approach for prediction and anomaly detection. In this study, we present the application of a model-driven method that employs a linear regression model to predict the future temperature, in real time, of accelerator magnets at the NSLS-II light source. This approach enables proactive identification of magnet-heating issues, facilitating magnet flushing prior to the occurrence of permanent damage without interrupting machine operation. The implementation of this method in the NSLS-II control room is described and the analysis of the online results is presented. The results demonstrate the model’s effectiveness in providing early alerts to engineers and improving the reliability of accelerator operations.

加速器磁体诊断模型驱动预测，提高运行可靠性

可靠性是加速器运行最关键的指标之一，特别是在用户设施中。为了减少昂贵的设施停机时间，并提供一个可以可靠预测系统性能的操作环境，以支持科学研究，我们正在开发一种模型驱动的预测和异常检测方法。在这项研究中，我们提出了一种模型驱动方法的应用，该方法采用线性回归模型来实时预测NSLS-II光源下加速器磁体的未来温度。这种方法可以主动识别磁铁加热问题，在发生永久性损坏之前促进磁铁冲洗，而不会中断机器操作。介绍了该方法在NSLS-II控制室中的实现，并对在线结果进行了分析。结果表明，该模型在为工程师提供早期预警和提高加速器运行可靠性方面是有效的。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
