Our approach utilizes a Long Short-Term Memory (LSTM) neural\u0000network to predict the temperature of key components within the magnet power\u0000supplies (PSs) of these accelerators, such as heatsinks, capacitors, and\u0000resistors, based on the electrical current flowing through the PS. Anomalies\u0000are declared when there is a significant discrepancy between the LSTM-predicted\u0000temperatures and actual observations. Leveraging a custom-built test stand, we\u0000conducted comprehensive performance comparisons with a less sophisticated\u0000method, while also fine-tuning hyperparameters of both methods. This process\u0000not only optimized the LSTM model but also unequivocally demonstrated the\u0000superior efficacy of this new proposed method. The dedicated test stand also\u0000facilitated exploratory work on more advanced strategies for monitoring\u0000interior PS temperatures using infrared cameras. A proof-of-concept example is\u0000provided.","PeriodicalId":501318,"journal":{"name":"arXiv - PHYS - Accelerator Physics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141169167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such colliders operate under a\u0000high disruption regime with an enormous number of electron-positron pairs\u0000produced from QED effects. Thus, it requires a self-consistent treatment of the\u0000fields produced by the pairs, which is not implemented in state-of-the-art\u0000beam-beam codes such as GUINEA-PIG. WarpX is a parallel, open-source, and\u0000portable particle-in-cell code with an active developer community that models\u0000QED processes with photon and pair generation in relativistic laser-beam\u0000interactions. However, its application to beam-beam collisions has yet to be\u0000fully explored. In this work, we benchmark the luminosity spectra, photon\u0000spectra, and coherent production process from WarpX against GUINEA-PIG in the\u0000ILC and ultra-tight collision scenarios.
