MO1BCO03	LCLS-II Accelerator Control System Status	controls, EPICS, MMI, linac	12
	D. Rogind, S. Kwon SLAC, Menlo Park, California, USA
	Funding: US DOE The Linac Coherent Light Source complex at the SLAC National Accelerator Laboratory has been upgraded to add a new superconducting accelerator with beam rates up to 1MHz. Though the majority of the more than twenty accelerator control systems are based on LCLS designs, to accommodate the increase in repetition rate from 120Hz to 1MHz, many of the diagnostics and global control systems are upgraded to high performance platforms with standalone CPUs running linuxRT to host the EPICS based controls. With installation and checkouts for control systems completing in 2022, the phased approach to integration and commissioning recently completed with demonstration of the threshold key performance parameters and first light occurring in the Summer of 2023. This paper provides an overview of the LCLS-II accelerator control system architecture, upgrades, the multi-year installation, checkout, integration, commissioning, and lessons learned.

TUPDP013	Status on Continuous Scans at BESSY II	controls, software, hardware, interface	513
	N. Greve, M. Brendike, D.K. Kraft, M. Neu, G. Pfeiffer HZB, Berlin, Germany
	Continuous energy scanning is an important feature for many beamlines at BESSY II. In 2015 this method was used at 11 Undulator and 6 dipol beamlines.[1] Since then the demand for this feature - especially among new build beamlines - increased, while the availability of the used hardware decreased. In order to tackle this problem, we investigate into alternative solutions for both, hardware and software. By introducing an independent high level controller between the two device controllers, we can compensate for communication incompatibilities and hence increase flexibility. This paper shows the status of our research. The ideas leading to a first prototype, the prototype itself and first results will be presented. [1] A. F.

TUPDP032	Reference Measurement Methods for Planar and Helical Undulators	vacuum, FEL, radiation, electron	575
	S. Karabekyan EuXFEL, Schenefeld, Germany
	The modern permanent magnet undulators are usually equipped with motors that have integrated feedback electronics. These are essentially rotary encoders that indicate the position of the motor axis. In addition, undulators are also equipped with linear encoders that provide the absolute value of the gap between the magnetic structures or the position of the magnetic girders relative to the undulator frame. The operating conditions of undulators should take into account the risks of failure of electronic equipment under the influence of radiation. In case of encoder failure, the motor or encoder must be replaced. To avoid the need to return the undulator to the magnetic measurement laboratory, reference measurements are required to restore the position of the magnetic structure after replacement. In this article, reference measurement procedures for planar and helical APPLE-X undulators used at the European XFEL are presented.

TUPDP127	SLAC LINAC Mode Manager Interface	linac, interface, timing, EPICS	882
	T. Summers, C. Bianchini Mattison, M. Gibbs, T.J. Kabana, P. Krejcik, J.A. Mock SLAC, Menlo Park, California, USA
	With the successful commissioning of the new superconducting (SC) LINAC, the LINAC Coherent Light Source (LCLS) now has the capability of interleaving beams from either the normal conducting (NC) LINAC or the SC LINAC to two different destinations, the soft (SXR) and hard (HXR) x-ray undulator beamlines. A mode manager user interface has been created to manage the beamline configuration to transport beam pulses to multiple destinations, which include the numerous intermediate tune-up dumps and safety dumps between the injectors and the final beam dumps. The mode manager interfaces with the timing system which controls the bunch patterns to the various locations, and the machine protection system which prevents excess beam power from being sent to the wrong destination. This paper describes the implementation method for handling the mode switching, as well as the operator user interface which allows users to graphically select the desired beam paths.

TUPDP145	Position-Based Continuous Energy Scan Status at MAX IV	controls, experiment, detector, synchrotron	917
	Á. Freitas, N.S. Al-Habib, B. Bertrand, M. Eguiraun, I. Gorgisyan, A.F. Joubert, J. Lidón-Simon, M. Lindberg, C. Takahashi MAX IV Laboratory, Lund University, Lund, Sweden
	The traditional approach of step scanning in X-ray experiments is often inefficient and may increase the risk of sample radiation damage. In order to overcome these challenges, a new position-based continuous energy scanning system has been developed at MAX IV Laboratory. This system enables stable and repeatable measurements by continuously moving the motors during the scan. Triggers are generated in hardware based on the motor encoder positions to ensure precise data acquisition. Prior to the scan, a list of positions is generated, and triggers are produced as each position is reached. The system uses Tango and Sardana for control and a TriggerGate controller to calculate motor positions and configure the PandABox, which generates the triggers. The system is capable of scanning a single motor, such as a sample positioner, or a combined motion like a monochromator and undulator. In addition, the system can use the parametric trajectory mode of IcePAP driver, which enables continuous scans of coupled axes with non-linear paths. This paper presents the current status of the position-based continuous energy scanning system for BioMAX, FlexPES, and FinEst beamlines at MAX IV and discusses its potential to enhance the efficiency and accuracy of data acquisition at beamline endstations.
