	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.

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.
