T2K is a second generation long-baseline experiment in Japan, designed to perform precision studies of neutrino oscillations. A neutrino beam originating at the J-PARC facility is sampled by two near detectors, approximately 280m distant from the source and directed towards the Kamioka underground facility, 295km distant, where the Super-Kamiokande water Cerenkov detector is situated. Both the on-axis...
The tracker of the near detector in the T2K neutrino oscillation experiment comprises three time projection chambers based on micro-pattern gaseous detectors. A new readout system is being developed to amplify condition and acquire in real time the data produced by the 124,000 detector channels. The cornerstone of the system is a 72-channel application specific integrated circuit which is based on...
NOnuA (E929) is a long baseline experiment that will search for neutrino oscillations. There will be one detector near the beam source at Fermilab, and one detector in northern Minnesota. The DAQ system for the far detector collects over-threshold hits from over 450,000 channels of scintillator readouts, sorts the time-stamped data packets and archives selected time periods of data for transmission...
In preparation for NOvA, a future neutrino experiment at Fermilab, we are developing a system for passing control and status messages in the data acquisition system. The DAQ system will consist of applications running on approximately 450 nodes. The message passing system will use a publish-subscribe model and will provide support for sending messages and receiving the associated replies. Additional...
