“…In the aftermath of this catastrophe, a decision was made not to end SK, though it would take considerable time to acquire the PMTs necessary to replace the destroyed During summer 2008, an electronics upgrade was performed [78]. A major motivation for this upgrade was to prepare for T2K.…”

T2K (Tokai to Kamioka) is a long baseline neutrino experiment with the primary goal of measuring the neutrino mixing angle θ 13 . It uses a muon neutrino beam, produced at the J-PARC accelerator facility in Tokai, sent through a near detector complex on its way to the far detector, Super-Kamiokande. Appearance of electron neutrinos at the far detector due to oscillation is used to measure the value of θ 13 .

“…TIME SYNCHRONIZATION WITH SUPER-K The beamline DAQ system sends the absolute time of beam extraction measured by the LTC and the spill number to the far detector, SK, to record the data even if no hit is observed at SK. SK continuously samples and stores data in its memory buffer using its unique DAQ system [8], [9], with the software trigger deciding whether these data should be recorded in storage. The SK DAQ system replies to timestamps sent from J-PARC, and these replies are monitored and recorded by the beamline DAQ system to evaluate transmission stability.…”

The T2K (Tokai-to-Kamioka) experiment is a long baseline neutrino experiment designed to observe oscillations from mu neutrinos to electron neutrinos. Through 2013, the system showed stable operation, with 230 kW of beam power and protons per bunch, the highest intensity in the world. This manuscript describes the data acquisition system used to monitor the high-intensity proton beam that produces the neutrino beam. This paper describes the data acquisition system for the monitoring of the primary proton beam and the secondary muon beam.

The T2K experiment is a long baseline neutrino oscillation experiment. Its main goal is to measure the last unknown lepton sector mixing angle θ13θ13 by observing νeνe appearance in a νμνμ beam. It also aims to make a precision measurement of the known oscillation parameters, View the MathML sourceΔm232 and sin22θ23sin22θ23, via νμνμ disappearance studies. Other goals of the experiment include various neutrino cross-section measurements and sterile neutrino searches. The experiment uses an intense proton beam generated by the J-PARC accelerator in Tokai, Japan, and is composed of a neutrino beamline, a near detector complex (ND280), and a far detector (Super-Kamiokande) located 295 km away from J-PARC. This paper provides a comprehensive review of the instrumentation aspect of the T2K experiment and a summary of the vital information for each subsystem
