The DAQ and control software system at the PAL-XFEL. (a) A schematic diagram of the DAQ system at PAL-XFEL. Based on the event timing system, each X-ray pulse is named by a time-stamp and all operations are synchronized by trigger signals. Home-built control software transmit queues to operate single equipment or plural ones. (b) In-house developed main control panel. It executes queues for motion movement and data collection. (c) A panel of the data viewer. It displays collecting data in real time and provides a sorting function for pump–probe experiments. The upper graph shows pump-on and pump-off data together and the lower one displays the result of the arithmetic operation. Here, it shows the differences between two data sets.
