Upper Limit on the Diffuse νμ\nu_\mu Flux with the ANTARES Telescope

A search for very-high energy cosmic muon neutrinos from unresolved sources is presented using data collected by the ANTARES neutrino telescope. Data corresponding to 334 days of equivalent live time show that the observed number of events is compatible with the expected number of background events. A 90% c.l. upper limit on the diffuse $\nu_\mu$ flux is set at E^2\Phi_{90%} = 5.3 \times 10^{-8} \ \mathrm{GeV\ cm^{-2}\ s^{-1}\ sr^{-1}} in the energy range 20 TeV -- 2.5 PeV.Comment: Poster presented at Neutrino 2010, Athens, Greec

Meaurement of Cosmic Ray elemental composition from the CAKE balloon experiment

CAKE (Cosmic Abundances below Knee Energies) was a prototype balloon experiment for the determination of the charge spectra and of abundances of the primary cosmic-rays (CR) with Z$>$10. It was a passive instrument made of layers of CR39 and Lexan nuclear track detectors; it had a geometric acceptance of $\sim$0.7 m$^2$sr for Fe nuclei. Here, the scanning and analysis strategies, the algorithms used for the off-line filtering and for the tracking in automated mode of the primary cosmic rays are presented, together with the resulting CR charge distribution and their abundances.Comment: 5 pages, 8 figure
