  1. T2K Data Acquisition System Matt Thorpe STFC Rutherford Appleton Laboratory 17th IEEE Real-Time Conference 2010, Lisbon, Portugal

  2. The T2K Experiment T2K Collaboration: ~450 collaborators, 65 institutes, 12 countries

  3. Super-Kamiokande far detector

  4. T2K Near Detectors ND280 INGRID

  5. T2K Near Detectors ND280 INGRID

  6. T2K NM pit - 26/11/2009

  7. Scintillator geometries P0D INGRID FGD SMRD

  8. Multi-Pixel Photon Detectors

  15. Back-end Board (BEB) 512MB DDR2 Optical I/O Virtex II Pro FPGA 48x LVDS I/O PROM (x2), JTAG

  16. DAQ System Architecture

  17. Front-end Processing Node (FPN)

  18. Front-end Processing Node (FPN)

  19. Front-end Processing Node (FPN)

  20. Front-end Processing Node (FPN)

  21. MIDAS Back-end Processes

  22. First INGRID cosmic event Single module cosmic event, 2009

  23. Neutrino interaction in the P0D sub-detector

  24. Conclusions • DAQ successfully used to commission all current ND280 detectors with multiple sub-detectors commissioned and calibrated simultaneously • Also deployed as QA DAQ systems for module production • DAQ ready to accept INGRID diagonal modules and ECAL P0D & barrel modules summer-autumn 2010 • Now in daily use for beam data taking • Data rates to tape are within acceptable limits • CPU load on FPNs low (~5% RXT, ~10% DPT)

  25. Thank you!
