Design studies for a long base-line neutrino beam

Strong interest has recently been shown in very long base-line neutrino beams, directed at existing or planned massive detector facilities, in order to extend the search for neutrino oscillations. Among such possibilities are beams from CERN pointing towards the Gran Sasso Underground Laboratory in the Ionian Sea off the west coast of the Peloponnese. In order to establish the basic parameters, a number of possible configurations for such beams have been studies covering a range of neutrino energy bands, estimates of the neutrino fluxes, event rates and backgrounds at typical detectors are reported. Considerations have been gioven to the optimum lenght and radius of the decay tunnels. It is shown that with one year of operation, a neutrino oscillation search down to limits of sin2 Ø = 0.01 and m2 = 0.001eV2 could be made with currently proposed detectors

MEMPHYS:A large scale water Cerenkov detector at Fr\'ejus

A water \v{C}erenkov detector project, of megaton scale, to be installed in the Fr\'ejus underground site and dedicated to nucleon decay, neutrinos from supernovae, solar and atmospheric neutrinos, as well as neutrinos from a super-beam and/or a beta-beam coming from CERN, is presented and compared with competitor projects in Japan and in the USA. The performances of the European project are discussed, including the possibility to measure the mixing angle $\theta_{13}$ and the CP-violating phase $\delta$.Comment: 1+33 pages, 14 figures, Expression of Interest of MEMPHYS projec

First results from the Development of a New Generation of Hybrid Photon Detectors: EBCMOS

International audienceThe proximity focusing Hybrid Photon Detector (HPD) concept is implemented to develop a single photon sensitive Electron Bombarded CMOS (EBCMOS). The first demonstrator has been produced by the collaboration between the EBCMOS group of IPNL, the CMOS sensor group of IPHC and the R&D department of PHOTONIS. The prototype characteristics (dark current, gain, spatial and energy resolutions) are presented. The futur developments of this type of photo detector are discussed
