TI - Remote User Operation with Karabo at the European XFEL J2 - Proc. of ICALEPCS2021, Shanghai, China, 14-22 October 2021 CY - Shanghai, China T2 - International Conference on Accelerator and Large Experimental Physics Control Systems T3 - 18 LA - english AB - At the European XFEL, scientific instruments are operated using the Karabo control system which has been developed in-house to serve the need of a tight integration of experiment control, data acquisition and data processing for fast experimental feedback. Karabo uses broker-based communication between its pluggable components, so-called devices. The generic, PyQt-based graphical user interface (GUI) interacts with the system via a TCP connection to a GUI server device. The travel and contact restrictions enacted in response to the COVID-19 pandemic have prevented many facility users from coming on site. In order to enable an easier remote user participation in experiments, a read-only version of the GUI server has been developed ad-hoc, and made available during Summer 2020. Obviously, easy and safe remote access has advantages beyond the current travel restrictions. Therefore, activities to provide a web-technology based front-end to Karabo have been accelerated. Perspectively, this interface aims to ensure remote accessibility, while conforming to scientific data and general privacy policies relevant for the European XFEL.
