	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.

TH2BCO01	Synchronized Nonlinear Motion Trajectories at MAX IV Beamlines	1160
	P. Sjöblom, H. Enquist, Á. Freitas, J. Lidón-Simon, M. Lindberg, S. Malki MAX IV Laboratory, Lund University, Lund, Sweden
	The motions at beamlines sometimes require components to move along non-trivial and non-linear paths. This type of motion can be achieved by combining several simple axes, typically linear and rotation actuators, and controlling them to perform synchronized motions along individual non-linear paths. A good example is the 10-meter-long spectrometer at MAX IV Veritas beamline, operating under the Rowland condition. The system consists of 6 linked axes that must maintain the position of detectors while avoiding causing any damage to the mechanical structure. The nonlinear motions are constructed as a trajectory through energy or focus space. The trajectory changes whenever any parameter changes or when moving through focus space at fixed energy instead of through energy space. Such changes result in automated generation and uploading of new trajectories. The motion control is based on parametric trajectory functionality provided by IcePAP. Scanning and data acquisition are orchestrated through Tango and Sardana to ensure full motion synchronization and that triggers are issued correctly.

	This paper describes the design and implementation of the control system for the ForMAX beamline at the MAX IV synchrotron. MAX IV is a Swedish national laboratory that houses one of the brightest synchrotron light sources in the world. ForMAX is one of the beamlines at MAX IV and is funded by the Knut and Alice Wallenberg Foundation and Swedish industry via Treesearch. To meet the specific demands of ForMAX, a new control system was developed using the TANGO Controls and Sardana frameworks. Using these frameworks enables seamless integration of hardware and software, ensuring efficient and reliable beamline operation. The control system was designed to support a variety of experiments, including multiscale structural characterization from nanometer to millimeter length scales by combining full-field tomographic imaging, small- and wide-angle X-ray scattering (SWAXS), and scanning SWAXS imaging in a single instrument. The system allows for precise control of the beam position, energy, intensity, and sample position. Furthermore, the system provides real-time feedback on the status of the experiments, allowing for adjustments to be made quickly and efficiently. In conclusion, the design and implementation of the control system for the ForMAX beamline at the MAX IV synchrotron has resulted in a highly flexible and efficient experimental station. TANGO Controls and Sardana have allowed for seamless integration of hardware and software, enabling precise and reliable control of the beamline for a wide range of experiments.

THPDP054	Fast, Fully Automated Continuous Energy Scan at the Biomax Beamline at Max IV Laboratory

	BioMAX is an X-ray macromolecular crystallography (MX) beamline* at MAX IV Laboratory that delivers an X-ray beam with a photon flux of up to 1e13 ph/s. The photon energy at the beamline can be easily adjusted between 6 keV and 24 keV. At MX beamlines Single- and Multi-wavelength Anomalous Dispersion (SAD and MAD) methods are used for experimental phasing to reconstruct the macromolecular structures. To be able to benefit from these techniques, it is imperative for an MX beamline to have a fast and automated energy scan routine. This contribution reports on the newly implemented continuous energy scan procedure at BioMAX. The scan routine performs a synchronous motion of the undulator and monochromator motors to continuously scan the energy while measuring the fluorescence from the sample as the energy changes. The data acquisition during the scan is triggered by the actual energy value which is monitored throughout the scan at 1 MHz rate. The energy scan routine is fully automated and minimizes the radiation damage on the sample during the measurements. The scan itself is as short as one second making the overall procedure a factor of five faster than a conventional step scan. * Ursby T. et al.
