TU2AO02	Textual Analysis of ICALEPCS and IPAC Conference Proceedings: Revealing Research Trends, Topics, and Collaborations for Future Insights and Advanced Search	309
	A. Sulc, A. Eichler, T. Wilksen DESY, Hamburg, Germany
	Funding: This work was supported by HamburgX grant LFF-HHX-03 to the Center for Data and Computing in Natural Sciences (CDCS) from the Hamburg Ministry of Science, Research, Equalities and Districts. In this paper, we show a textual analysis of past ICALEPCS and IPAC conference proceedings to gain insights into the research trends and topics discussed in the field. We use natural language processing techniques to extract meaningful information from the abstracts and papers of past conference proceedings. We extract topics to visualize and identify trends, analyze their evolution to identify emerging research directions and highlight interesting publications based solely on their content with an analysis of their network. Additionally, we will provide an advanced search tool to better search in the existing papers to prevent duplication and easier reference findings. Our analysis provides a comprehensive overview of the research landscape in the field and helps researchers and practitioners to better understand the state-of-the-art and identify areas for future research.

TUPDP024	Technical Design Concept and First Steps in the Development of the New Accelerator Control System for PETRAIV	552
	R. Bacher, J.D. Behrens, T. Delfs, T. Tempel, J. Wilgen, T. Wilksen DESY, Hamburg, Germany
	At DESY, extensive technical planning and prototyping work is currently underway for the upgrade of the PETRAIII synchrotron light source to PETRAIV, a fourth-generation low-emittance machine. As part of this planned project, the accelerator control system will also be modernized. This paper reports on the main decisions taken in this context and gives an overview of the scope of the development and implementation work.

TH2AO01	Log Anomaly Detection on EuXFEL Nodes	1126
	A. Sulc, A. Eichler, T. Wilksen DESY, Hamburg, Germany
	Funding: This work was supported by HamburgX grant LFF-HHX-03 to the Center for Data and Computing in Natural Sciences (CDCS) from the Hamburg Ministry of Science, Research, Equalities and Districts. This article introduces a method to detect anomalies in the log data generated by control system nodes at the European XFEL accelerator. The primary aim of this proposed method is to offer operators a comprehensive understanding of the availability, status, and problems specific to each node. This information is vital for ensuring the smooth operation. The sequential nature of logs and the absence of a rich text corpus that is specific to our nodes pose a significant limitation for traditional and learning-based approaches for anomaly detection. To overcome this limitation, we propose a method that uses word embedding and models individual nodes as a sequence of these vectors that commonly co-occur, using a Hidden Markov Model (HMM). We score individual log entries by computing a probability ratio between the probability of the full log sequence including the new entry and the probability of just the previous log entries, without the new entry. This ratio indicates how probable the sequence becomes when the new entry is added. The proposed approach can detect anomalies by scoring and ranking log entries from EuXFEL nodes where entries that receive high scores are potential anomalies that do not fit the routine of the node. This method provides a warning system to alert operators about these irregular log events that may indicate issues.

THPDP018	The Timing System for PETRA IV	1335
	T. Wilksen, V. Andrei, K. Brede, H.T. Duhme, M. Fenner, U. Hurdelbrink, J.M. Jäger, H. Kay, H. Lippek, F. Ludwig, M. Pawelzik, S. Ruzin, H. Schlarb DESY, Hamburg, Germany
	At DESY, the PETRA III synchrotron light source upgrade towards a fourth-generation, low-emittance machine PETRA IV is being pursued. The realisation of the new machine requires a complete redesign of the timing system, as the beam quality and beam control requirements will change significantly. The new timing system must generate and distribute facility-wide precise clocks, trigger signals, trigger events and beam-synchronous information. The design of the main hardware components will be based on the MTCA.4 standard, which has become a well-established platform at DESY and successfully been in use with DESY FEL’s MTCA.4-based timing systems for almost a decade now. This paper presents and discusses the PETRA IV timing system overall concept and functionality and its hardware components development status.
