Description
Operando synchrotron experiments require coordinated control of complex sample environments and beamline measurements over several days. These experiments are often run manually or through monolithic scripts, limiting flexibility and making live adaptation during beamtime difficult. Within the ROCK-IT project, we developed a Bluesky-based orchestration framework that represents experiments as machine-readable stages combining sample environment conditions with X-ray measurement routines. The framework uses two independent Bluesky Queueservers: an outer server controls experiment progression and sample environments, while an inner server executes editable beamline measurement loops. This hierarchical design allows measurements to be modified during operation without interrupting the experiment.
The framework was deployed for operando catalysis experiments at multiple facilities. We present methods for queue inspection, graphical recipe preview, and validation before execution, enabling safer unattended operation, live adaptation, and improved reproducibility.
