abstract = {{CoSAXS is the Coherent and Small Angle X-ray Scattering (SAXS) beamline placed at the diffraction-limited 3 GeV storage ring at MAX IV Laboratory. The beamline can deliver a very high photon flux ~10¹³ ph/s and it is equipped with state-of-the-art pixel detectors, suitable for experiments with a high time-resolution to be performed. In this work we present the upgraded beamline data acquisition strategy for a millisecond time-resolved SAXS/WAXS experiment, using laser light to induce temperature jumps or UV-excitation with the consequent structural changes on the system. In general terms, the beamline control system is based on TANGO and built on top of it, Sardana provides an advanced scan framework. In order to synchronize the laser light pulse on the sample, the X-ray fast shutter opening time and the X-ray detectors readout, hardware triggers are used. The implementation is done using PandABox, which generates the pulse train for the laser and for all active experimental channels, such as counters and detectors, in synchronization with the fast shutter opening time. PandABox integration is done with a Sardana Trigger Gate Controller, used to configure the pulses parameters as well to orchestrate the hardware triggers during a scan. This paper describes the experiment orchestration, laser light synchronization with multiple X-ray detector. }},
