	Funding: This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 871072 Badger* is a software designed to easily access several optimizers (simplex, RCDS*, bayesian optimization, etc.) to solve a given multidimensional minimization/maximization task. The Badger software is very flexible and easy to adapt to different facilities. In the framework of the EURIZON European project Badger was used for the EBS and PETRAIII storage rings interfacing with the Tango and TINE control system. Among other tests, the optimisations of Touschek lifetime was performed and compared with the results obtained with existing tools during machine dedicated times. Z.

TUPDP020	Summary Report on Machine Learning-Based Applications at the Synchrotron Light Source Delta	laser, controls, synchrotron, storage-ring	537
	D. Schirmer, S. Khan, A. Radha Krishnan DELTA, Dortmund, Germany
	In recent years, several control system applications using machine learning (ML) techniques have been developed and tested to automate the control and optimization of the 1.5 GeV synchrotron radiation source DELTA. These applications cover a wide range of tasks, including electron beam position correction, working point control, chromaticity adjustment, injection process optimization, as well as CHG-spectra (coherent harmonic generation) analysis. Various machine learning techniques have been used to implement these projects. This report provides an overview of these projects, summarizes the current results, and indicates ideas for future improvements.

TUPDP030	Integration of an Optimizer Framework into the Control System at KARA	controls, interface, storage-ring, framework	570
	C. Xu, E. Blomley, A.-S. Müller, A. Santamaria Garcia KIT, Karlsruhe, Germany M. Zhang PU, Princeton, New Jersey, USA
	Tuning particle accelerators is not straightforward, as they depend on a large number of non-linearly correlated parameters that, for example, drift over time. In recent years advanced numerical optimization tools have been developed to assist human operators in tuning tasks. A proper interface between the optimizers and the control system will encourage their daily use by the accelerator operators. In this contribution, we present our latest progress in integrating an optimizer framework into the control system of the KARA storage ring at KIT, allowing the automatic tuning methods to be applied for routine tasks.

TUPDP046	Beam Operation for Particle Physics and Photon Science with Pulse-to-Pulse Modulation at KEK Injector Linac	operation, linac, experiment, controls	627
	K. Furukawa, M. Satoh KEK, Ibaraki, Japan
	The electron and positron accelerator complex at KEK offers unique experimental opportunities in the fields of elementary particle physics with SuperKEKB collider and photon science with two light sources. In order to maximize the experimental performances at those facilities the injector LINAC employs pulse-to-pulse modulation at 50 Hz, injecting beams with diverse properties. The event-based control system effectively manages different beam configurations. This injection scheme was initially designed 15 years ago and has been in full operation since 2019. Over the years, quite a few enhancements have been implemented. As the event-based controls are tightly coupled with microwave systems, machine protection systems and so on, their modifications require meticulous planning. However, the diverse requirements from particle physics and photon science, stemming from the distinct nature of those experiments, often necessitate patient negotiation to meet the demands of both fields. This presentation discusses those operational aspects of the multidisciplinary facility.

THMBCMO32	Robotic Process Automation: on the Continuity of Applications Development at SOLEIL	PLC, laser, electron, synchrotron	1275
	L.E. Munoz, Y.-M. Abiven, M.-E. Couprie, A. Noureddine, J. Perez, A. Thureau, M. Valléau SOLEIL, Gif-sur-Yvette, France
	SOLEIL is currently in the Technical Design Report (TDR) phase of a major upgrade of the facility. In its digital transformation, the development of processes and systems with a high degree of autonomy is at the center of the SOLEIL II project. One of the important components used to achieve a high degree of autonomy is the use of 6-axis robotic arms. Thus, in recent years, SOLEIL has developed and put into operation robotic applications to automate some processes of its beamlines and some processes of magnetic measurements of the insertion devices. The last year SOLEIL has been developing two new robotic applications, having thus continuity in the development of applications using its robotic standard. This paper describes these two new applications that being developed to automate the injection of liquid samples for BioSAXS experiments at the SWING beamline and to automate the mechanical and magnetic adjustment of the modules that compose an insertion device.

THPDP057	SPS Beam Dump Enhancements on Tracking and Synchronization	kicker, controls, timing, operation	1444
	N. Voumard, N. Magnin, P. Van Trappen European Organization for Nuclear Research (CERN), Geneva, Switzerland
	During Long Shutdown 2 (LS2) at CERN, the SPS Beam Dumping System (SBDS) was completely renovated and relocated to SPS Point 5. This allowed to deploy at the SPS the Beam Energy Tracking System (BETS) and the Trigger Synchronization Unit (TSU), initially designed for and operational at the LHC Beam Dumping System (LBDS). The challenge encountered in this migration was the dynamic multi-cycle operation scheme with fast ramping cycles of the SPS in comparison to the long physics periods at stable energy of the LHC. This paper describes the modification of both BETS and TSU systems as well as the automatic arming sequence put in place, including the interactions with the SPS injection, the beam revolution frequency, and the Beam Interlock System (BIS).
