  1. 338. About the prototype of the KM3NeT DOM: First results
    Mr Tino Michael (Nikhef)

    Deep-sea and Deep-ice technologies
    The future KM3NeT neutrino telescope will consist of several thousand digital optical modules (DOM), each of which will be equipped with 31 3-inch photo-multiplier tubes. This design has various advantages, e.g. concerning effective photocathode area per module, background suppression and also directional reconstruction. Currently, KM3NeT is testing a prototype DOM deployed on the...

    Deep-sea and Deep-ice technologies
    The Precision IceCube Next Generation Upgrade (PINGU) will require optical sensors with performance similar to IceCube’s DOMs but implemented in a higher-density array. We are pursuing a new design for the "PDOM" that retains the proven mechanical elements of the IceCube DOM yet takes advantage of recently commercialized high-speed digitizer technology. The main features of the...

  3. 335. Development of the multi-PMT optical module for PINGU

    Deep-sea and Deep-ice technologies
    The IceCube large-volume neutrino telescope aims at the exploration of sources in the TeV energy range. A dense infill array, Deep Core, provides sensitivity to neutrinos of lower energy, down to about 20 GeV. One goal of the PINGU project is to add even denser instrumentation in the Deep Core subvolume and to further decrease the energy threshold of the instrument to a few GeV. As...

  4. 342. Opto-Acoustical Modules for KM3NeT
    Mr Alexander Enzenhöfer (ECAP, University of Erlangen)

    Deep-sea and Deep-ice technologies
    Accurate acoustic position calibration of the optical modules is a necessary prerequisite for neutrino telescope data analysis. For KM3NeT, the integration of the corresponding acoustic sensors into the optical modules is investigated. The combination of both sensor types inside one module reduces the complexity of the mechanical structures and interfaces to a minimum, leading to an...

  5. 337. PORFIDO: Oceanographic measurements on neutrino telescopes
    Dr Agnese Martini (INFN - LNF)
    06/08/2013, 17:20
    Deep-sea and Deep-ice technologies
    We have designed and built an underwater measurement system, PORFIDO (Physical Oceanography by RFID Outreach) to gather oceanographic data from the Optical Modules of a neutrino telescope with a minimum of disturbance to the main installation. PORFIDO is composed of a sensor glued to the outside of an Optical Module, in contact with seawater, and of a reader placed inside the sphere,...
