We report measurements of oscillation parameters from ν(μ) and disappearance using beam atmospheric data MINOS. The comprise exposures 10.71×10(20) protons on target in the ν(μ)-dominated beam, 3.36×10(20) ν(μ)-enhanced 37.88 kton yr neutrinos. Assuming identical ν parameters, we measure |Δm2| = (2.41(-0.10)(+0.09))×10(-3) eV2 sin2(2θ) 0.950(-0.036)(+0.035). Allowing independent oscillations, antineutrino (2.50(-0.25)(+0.23))×10(-3) 0.97(-0.08)(+0.03), with minimal change to neutrino parameters.
We report on ν(e) and appearance in ν(μ) beams using the full MINOS data sample. The comparison of these at a 735 km baseline with θ13 measurements by reactor experiments probes δ, θ23 octant degeneracy, mass hierarchy. This analysis is first use this technique includes accelerator long-baseline search for → ν(e).

We measure neutrino charged-current quasielasticlike scattering on hydrocarbon at high statistics using the wideband Neutrinos Main Injector beam with energy peaked 6 GeV. The double-differential cross section is reported in terms of muon longitudinal (p_{∥}) and transverse (p_{⊥}) momentum. Cross contours versus lepton momentum components are approximately described by a conventional generator-based simulation, however, discrepancies observed for momenta above 0.5 GeV/c ranges 3-5 9-20...
ICARUS T600 is the far detector of Short Baseline Neutrino program at Fermilab (U.S.A.), which foresees three Liquid Argon Time Projection Chambers along Booster Beam line to search for LSND-like sterile neutrino signal.

Abstract The ICARUS-T600 Liquid Argon (LAr) Time Projection Chamber (TPC) is presently taking data in the Short Baseline Neutrino (SBN) program at Fermilab (U.S.A.) to search for a possible LSND-like sterile neutrino signal Δ m 2 ≈ 1 eV with Booster Beam (BNB). A light detection system, based on 360 large area Photo-Multiplier Tubes (PMTs), has been realized detect VUV photons produced by passage of ionizing particles LAr. This system fundamental TPC operation, providing an efficient trigger...
We report the first observation of seasonal modulations in rates cosmic ray multiple-muon events at two underground sites, MINOS Near Detector with an overburden 225 mwe, and Far site 2100 mwe. At deeper site, muons separated by more than 8 m exhibit a rate that peaks during summer, similar to single-muon events. In contrast unexpectedly, less 5--8 m, smaller, shallower Detector, modulation winter.
The ICARUS T600 liquid argon (LAr) time projection chamber (TPC) underwent a major overhaul at CERN in 2016–2017 to prepare for the operation FNAL Short Baseline Neutrino (SBN) program. This included upgrade of photo-multiplier system and TPC wire read-out electronics. full electronics together with new biasing interconnection scheme are described. design signal feed-through flange is also fundamental piece this whose feature integration all components onto flange. Initial functionality...
Digital baseband and digital subcarrier noncoherent optical communication systems are considered in this paper. Expressions developed for the bit error probability of which use a nonliner polarization modulator either one-detector or two-detector receiver, The expressions evaluated numerically, results used to compare one- with corresponding fLxed probability.
The CDF experiment uses a three-level trigger system to select events produced during pp macr collisions. As the luminosity of Tevatron accelerator falls by factor four over 24 hour period, selections are adjusted automatically in order make full use data processing bandwidth. made maximize high purity triggers and keep deadtime as low possible at any given thoughout entire course run. We describe algorithms used obtain these goals how changing conditions accounted for analysis data.
