The TrainBuilder is an ATCA based data acquisition system developed at the STFC Rutherford Appleton Laboratory to provide readout for each of three Mega-pixel detectors at the European-XFEL Hamburg.
Each Train Builder system constructs over 5,000 detector images per second using FPGAs with DDR2 data buffering and an analogue crosspoint switch architecture; thereby processing 10 GBytes/sec of raw image data.
The system provides image processing, event formatting and data monitoring.
TrainBuilder I/O links to detectors operate using 10 Gigabit UDP protocols implemented in FPGA logic.
Four TrainBuilders are now being used to commission detectors for first X-ray beams in autumn 2017.
