Important open questions are still present in fundamental Physics and Cosmology, like the nature of Dark Matter, matter-antimatter asymmetry validity Standard Model particle interactions. Addressing these requires a new generation massive detectors to explore subatomic astrophysical worlds. ICARUS T600 is first large mass (760 tons) example able combine imaging capabilities old famous ``bubble chamber'' with excellent energy measurement huge electronic detectors. now operates at Gran Sasso...

The calorimeter, range detector and active target elements of the T2K near detectors rely on Hamamatsu Photonics Multi-Pixel Photon Counters (MPPCs) to detect scintillation light produced by charged particles. Detailed measurements MPPC gain, afterpulsing, crosstalk, dark noise, photon detection efficiency for low levels are reported. In order account impact behavior physics observables, a simulation program has been developed based these measurements. is used predict energy resolution detector.

The CERN-SPS accelerator has been briefly operated in a new, lower intensity neutrino mode with ~10^12 p.o.t. /pulse and beam structure made of four LHC-like extractions, each narrow width 3 ns, separated by 524 ns. This very tightly bunched represents substantial progress respect to the ordinary operation CNGS beam, since it allows accurate time-of-flight measurement neutrinos from CERN LNGS on an event-to-event basis.

Liquid Argon Time Projection Chamber (LAr TPC) detectors offer charged particle imaging capability with remarkable spatial resolution. Precise event reconstruction procedures are critical in order to fully exploit the potential of this technology.

The ICARUS T600 detector, the largest liquid Argon Time Projection Chamber (LAr-TPC) realized after many years of R&D activities, was installed and successfully operated for 3 at INFN Gran Sasso underground Laboratory. One most important issues need an extremely low residual electronegative impurity content in Argon, order to transport free electrons created by ionizing particles with very small attenuation along drift path. solutions adopted recirculation purification systems have permitted...
The OPERA collaboration has claimed evidence of superluminal {\nu}{_\mu} propagation between CERN and the LNGS. Cohen Glashow argued that such neutrinos should lose energy by producing photons e+e- pairs, through Z0 mediated processes analogous to Cherenkov radiation. In terms parameter delta=(v^2_nu-v^2_c)/v^2_c, result implies delta = 5 x 10^-5. For this value \delta a very significant deformation neutrino spectrum an abundant production pairs be observed at We present analysis based on...
