Neutrino interaction in the P0D sub-detector
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)
Thank you!
