Intense and complex instrumental backgrounds, against which the much smaller signals from celestial sources have to be discerned, are a notorious problem for low and intermediate energy γ-ray astronomy (∼ 50 keV – 10 MeV). Therefore a detailed qualitative and quantitative understanding of instrumental line and continuum backgrounds is crucial for most stages of γ-ray astronomy missions, ranging...

CHORUS is an experiment primarily designed to search for νμ → ντ oscillations in the CERN wide-band neutrino beam. It also aims to investigate a wide range of charm physics. In four years of exposure, more than 10 neutrino interactions have been accumulated in the emulsion target, out of which several thousands lead to the production of a charmed particle. Using its massive calorimeter as a tar...

A precision measurement of atmospheric electron fluxes has been performed on a Japanese commercial airliner (Enomoto, et al., Ref. [1]). The bulk of these electrons are produced in pairs from the gamma rays emitted when π0s decay, which in turn have been produced in cosmic ray-air nucleus collisions. These electron fluxes can be used to test elements of our atmospheric neutrino flux calculation...

ABSTARCT The quark-gluon matter produced in RHIC collisions has high s-quark content [1]. This suggests an equally high probability of Ds mesons formation during the different decay processes. We reconstructed Ds mesons using data from earlier runs; these encompass about ten thousand events. We also investigated the significance of the reconstructed signal as well as the efficiency of the metho...

The IPv6 has experienced a slow progress. However the inexistence of studies in this area does not aid in the understanding of its true evolution. Without the necessary measuring tools it is not possible to assess IPv6’s dissemination and ultimately its success or failure. In this paper an initial study of the IPv6 integration in the Portuguese academic network is provided. This study is part o...

We discuss the design and performance of a threshold Cerenkov counter for identiication of charged hadrons. The radiator is pressurized gas, which is contained in thin-walled cylindrical modules. A mirror system of novel design transports Cerenkov photons to photomultiplier tubes. This system is compact, contains relatively little material, and has a large fraction of active volume. A prototype...

Information Centric Networking (ICN) architectures are currently being investigated to orient the Future Internet towards a content centric paradigm, thus allowing the provisioning of more secure, efficient, and scalable services. In this work, we focus on the Named Data Networking (NDN) proposal to analyze the impact of several routing and forwarding strategies, which play a fundamental role i...
