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...
A dedicated test of the effects Nitrogen contamination in liquid Argon has been performed at INFN-Gran Sasso Laboratory (LNGS, Italy) within WArP R&D program. detector designed and assembled for this specific task connected to a system injection controlled amounts gaseous into Argon.

We report an early result from the ICARUS experiment on search for a ν μ →ν e signal due to LSND anomaly. The was performed with T600 detector located at Gran Sasso Laboratory, receiving CNGS neutrinos CERN average energy of about 20 GeV, after flight path ∼730 km. anomaly would manifest as excess events, characterized by fast oscillation averaging approximately $\sin^{2}(1.27\Delta m^{2}_{\mathrm{new}}L/E_{\nu})\approx 1/2$ probability $P_{\nu_{\mu}\rightarrow \nu_{e}} = 1/2...
A dedicated test of the effects Oxygen contamination in liquid Argon has been performed at INFN-Gran Sasso Laboratory (LNGS, Italy) within WArP R&D program. Two detectors have used: 2.3 lt prototype and a small (0.7 lt) detector, coupled with system for injection controlled amounts gaseous Oxygen. Purpose 0.7 detector is to detect reduction long-lived component lifetime scintillation light emission increasing O2 concentration. Data from are used determining behavior both ionization electron...
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. ICARUS T600 detector collected 7 beam-associated events, consistent...
A bstract During May 2012, the CERN-CNGS neutrino beam has been operated for two weeks a total of ~1.8 × 10 17 p.o.t., with proton made bunches, few ns wide and separated by 100 ns. This structure allows very accurate time flight measurement neutrinos from CERN to LNGS on an event-by-event basis. Both ICARUS-T600 PMT-DAQ CERN-LNGS timing synchronization have substantially improved this campaign, taking advantage additional independent GPS receivers, both at as well deployment “White Rabbit”...
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. In paper we present a new, general approach 3D for LAr TPC practical application track reconstruction. The efficiency method is evaluated on sample simulated tracks. We also analysis stopping tracks collected during ICARUS T600 detector operation...

Four clear {\nu}e have been visually identified over full sample, compared expectation 6.4 +- 0.9 conventional sources. compatible absence...
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...
