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...

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...

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...

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,...
