The NA62 RICH detector

The RICH detector of the NA62 experiment is proposed for pion - muon separation and to contribute to the first level of the trigger. The design parameters of the detector and the results of test beams performed at CERN in 2007 and 2009 with a prototype are presented.Comment: 3 pages, 2 figures, To appear in the proceedings of 12th Topical Seminar on Innovative Particle and Radiation Detectors (IPRD10), Siena, Italy, 7-10 June 201

The Antares neutrino detector

The Antares neutrino telescope, operating at 2.5 km depth in the Mediterranean Sea, 40km off the Toulon shore, represents the worlds largest operational underwater neutrino telescope, optimised for the detection of Cherenkov light produced by neutrino-induced muons. The neutrinos momentum is transferred to the muons allowing for reconstruction of the direction of the neutrino. The main goal of Antares is the search of high-energy neutrinos from astrophysical point or transient sources. Antares has been taking data in its full 12 lines configuration since May 2008: in these Proceedings the description of the detector and its performances will be presented while first preliminary results on neutrino events will be discussed

Quasi-elastic and inelastic inclusive electron scattering from an oxygen jet target

The results of an experiment on inclusive electron scattering from an oxygen jet target, performed in a wide range of energy and momentum transfer covering both quasi-elastic and $\Delta$(1232) resonance regions, are reported. In the former region the theoretical predictions, obtained including effects of nucleon-nucleon correlations in both initial and final states, give a good description of the experimental data. In the inelastic region a broadening as well as a damping of the resonant part of the cross section with respect to the free nucleon case is observed. The need of more detailed calculations including nuclear structure effects on the electroproduction cross section of nucleon resonances is highlighted.Comment: to appear in Nucl. Phys.

Annealing of radiation induced defects in silicon in a simplified phenomenological model

The concentration of primary radiation induced defects has been previously estimated considering both the explicit mechanisms of the primary interaction between the incoming particle and the nuclei of the semiconductor lattice, and the recoil energy partition between ionisation and displacements, in the frame of the Lindhard theory. The primary displacement defects are vacancies and interstitials, that are essentially unstable in silicon. They interact via migration, recombination, annihilation or produce other defects. In the present work, the time evolution of the concentration of defects induced by pions in medium and high resistivity silicon for detectors is modelled, after irradiation. In some approximations, the differential equations representing the time evolution processes could be decoupled. The theoretical equations so obtained are solved analytically in some particular cases, with one free parameter, for a wide range of particle fluences and/or for a wide energy range of the incident particles, for different temperatures; the corresponding stationary solutions are also presented.Comment: 14 pages, 5 figures, accepted to Nuclear Instruments and Methods in Physics Research B second version, major revisio

The proton structure function F2 in the resonance region

Unique measurement of the proton structure function F2 in a wide two-dimensional region of x and Q**2 has been reported. The accessible kinematics covers entire resonance region up to W=2.5 GeV in the Q**2 interval from 0.1 to 4.5 GeV**2. Obtained data allowed for the first time an evaluation of moments of the structure function F2 directly from experimental data as well as an intensive study of the Bloom-Gilman duality phenomenon.Comment: 6 pages, 4 figures, Proceedings of GDH2002 Conference, 3-6 July 2002, Genova, Italy, to be published in World Scientifi
