The KM3NeT research infrastructure being built at the bottom of Mediterranean Sea will host water-Cherenkov telescopes for detection cosmic neutrinos. neutrino consist large volume three-dimensional grids optical modules to detect Cherenkov light from charged particles produced by neutrino-induced interactions. Each module houses 31 3-in. photomultiplier tubes, instrumentation calibration signal and positioning module, all associated electronics boards. By design, total electrical power...
The NEMO Phase-2 tower is the first detector which was operated underwater for more than 1 year at "record" depth of 3500 m. It designed and built within framework (NEutrino Mediterranean Observatory) project. 380 m high successfully installed in March 2013 80 km offshore Capo Passero (Italy). This prototype on site where Italian node KM3NeT neutrino telescope will be built. installation operation has proven functionality infrastructure operability depth. A long monitoring deep water...
Abstract In the deep sea, sense of time is dependent on geophysical fluctuations, such as internal tides and atmospheric-related inertial currents, rather than day-night rhythms. Deep-sea neutrino telescopes instrumented with light detecting Photo-Multiplier Tubes (PMT) can be used to describe synchronization bioluminescent activity abyssopelagic organisms hydrodynamic cycles.

A 13-inch Optical Module (OM) containing a large-area (10-inch) photomultiplier was designed as part of Phase-2 the NEMO project. An intense R&D activity on photomultipliers, voltage supply boards, optical coupling well study influences Earth's magnetic field has driven choice each single component OM. Following well-established production procedure, 32 OMs were assembled and their functionality tested. The design, testing phases are thoroughly described in this paper.
The Vacuum Silicon PhotoMultiplier Tube (VSiPMT) is an innovative design we propose for a modern hybrid photodetector based on the combination of (SiPM) with hemispherical vacuum glass PMT standard envelope. basic idea to replace classical dynode chain SiPM, which acts as electron multiplying detector. Such solution will match goal large photocathode sensitive area performances SiPM. This lead many advantages such lower power consumption, mild sensitivity magnetic fields and high quantum...

Data reduction completely performed Portopalo shore station dedicated computing facility connected...
Since the early days of experimental particle physics photomultipliers (PMTs) have played an important role in detector design. Thanks to their capability fast photon counting, PMTs are extensively used new-generation astroparticle experiments, such as air, ice and water Cherenkov detectors. Small size (⩽ 3 inches diameter) show little sensitivity Earth magnetic field, small transit time, stable time spread; price per photocathode area is less comparing one for large PMTs, typically so far...
Since almost a century photomultipliers have been the main sensors for photon detection in nuclear and astro-particle physics experiments. In recent years search cosmic neutrinos gave birth to enormous size experiments (Antares, Kamiokande, Super-Kamiokande, etc.) even kilometric scale as ICECUBE future KM3NeT. A very large volume neutrino telescope like KM3NeT requires several hundreds of thousands photomultipliers. The performance strictly depends on each PMT. For this reason, it is...

In astroparticle physics photomultiplier tubes play a crucial role in the detection of fundamental physical processes. After about one century standard technology (photocathode and dynode electron multiplication chain), recent strong development modern silicon devices has brought to maturity new generation photodetectors based on an innovative, high-quality, cost effective technology. particular most promising this field is represented by rapidly emerging CMOS p-n Geigermode avalanche...
