Description
At the European XFEL, the inhouse developed Supervisory Control and Data Acquisition System (SCADA) Karabo has been steering and facilitating scientific experiments at the photon beamlines since the free-electron laser started its operation in 2017.
A single Graphical User Interface (GUI), the so-called KaraboGui, has been designed as a multi-purpose application and is the preferred entry point to the control system. Implementing a nowadays standard event-driven asynchronous server-client approach, this application based on Python [2] and Qt [3] is the prime choice for hardware and experiment control and as well configuring detector calibration and data acquisition. Equipped with a generic panel builder and a package updater for external component extensions, the KaraboGui matches the requirements of a present and future graphical user interface for the experiments.
All user-interface panels build in the KaraboGui can be translated into a Scalable Vector Graphics (SVG) representation and loaded or edited with an SVG graphics program (e.g. Inkscape [4]).
This contribution describes in detail the client application KaraboGui and its usage at the European XFEL with an outlook of a web representation.
