MOCPL02	Modernization of Experimental Data Taking at BESSY II	65
	R. Müller, A.F. Balzer, P. Baumgärtel, G. Hartmann, O.-P. Sauer, J. Viefhaus HZB, Berlin, Germany
	The modernization approach for the automation of experimental data taking at BESSY II will be based on the data model of devices. Control of new components and refactoring and reassembly of legacy software should fit into a device based framework. This approach guides the integration of motors, encoders, detectors and auxiliary subsystems. In addition modern software stacks are enabled to provide automation tools for beamline and experimental flow control and DAQ. Strategic goal is the mapping of real beamline components into modelling software to provide the corresponding digital twin. First tests applying DMA methods within this context for tuning are promising.

TUCPL01	Adding Machine Learning to the Analysis and Optimization Toolsets at the Light Source BESSY II	754
	L. Vera Ramirez, T. Mertens, R. Müller, J. Viefhaus HZB, Berlin, Germany G. Hartmann University of Kassel, Kassel, Germany
	The Helmholtz Association has initiated the implementation of the Data Management and Analysis concept across its centers in Germany. At Helmholtz-Zentrum Berlin, both the beamline and the machine (accelerator) groups have started working towards setting up the infrastructure and tools to introduce modern analysis, optimization, automation and AI techniques for improving the performance of the (large scale) user facility and its experimental setups. This paper focuses on our first steps with Machine Learning techniques over the past months at BESSY II as well as organizational topics and collaborations. The presented results correspond to two complementary scenarios. The first one is based on supervised ML models trained with real accelerator data, whose target are real-time predictions for several measurements (lifetime, efficiency, beam loss, …); some of these techniques are also used for additional tasks such as outlier detection or feature importance analysis. The second scenario includes first prototypes towards self-tuning of machine parameters in different optimization cases (injection efficiency, orbit correction, …) with Deep Reinforcement Learning agents.

	BERLinPro is an energy recovery linac (ERL) demonstrator project built at HZB. It features CW SRF technology for the low emittance, high brightness gun, the booster module and the recovery linac. Construction and civil engineering are mostly completed. Synchronized with the device integration the EPICS based control system is being set-up for testing, commissioning and finally operation. In the warm part of the accelerator technology that is already operational at BESSY and MLS (e.g. CAN-bus and PLC/OPCUA) is used. New implementations like the machine protection system and novel major subsystems (e.g. LLRF, Cryo-Controls, photo cathode laser) need to be integrated. The first RF transmitters have been tested and commissioned. At the time of this conference the first segment of the accelerator is scheduled to become online. For commissioning and operation of the facility the standard set of EPICS tools form the back-bone.
