MHz X-ray Microscopy is a becoming a major type of user experiments at the European XFEL (EuXFEL) beeing performed at different hard X-ray SASE instruments. Recently, MHz X-ray Microscopy / Phase Contrast imaging setup was fully integrated and implemented at the EuXFEL within the Karabo control system. This includes controls for motors, timing system for triggering and synchronization, fast and slow cameras, analogue to digital converters, fast X-ray detectors, and data acquisition (DAQ) system. All the aforementioned devices and the DAQ system work seamlessly together. Further a more complex setup like the MHz Tomoscopy was integrated. With interest for these imaging methodologies increasing at other free electron lasers and synchrotrons, we have started to perform experiments at other facilities like ESRF and LCLS. However, these facilities lack a fully integrated control and DAQ infrastructure for fast X-ray Microscopy. With this in mind, we have implemented a standalone Karabo control and DAQ infrastructure for MHz X-ray microscopy methodologies. This setup includes all the devices that are integrated in Karabo for X-ray imaging experiments, including the fast cameras, timing system, direct conversion detectors like the Jungfrau 1M, motor controllers including 70+ axis controller for MHz Tomoscopy prototype, and DAQ. Initial tests indicate reliable performance.
This contribution describes the deployment and maintenance of the Karabo control system for this standalone setup and application possibilities at other facilities.
