HELYCON & NEUTRINO ASTROPARTICLE PHYSICS


Neutrino Telescopy is a new field of research in Astroparticle Physics, emerging at the intersection of Particle Physics, Astrophysics, and Cosmology.  The observation of astrophysical high energy neutrinos makes it possible to probe the most luminous and energetic objects in the universe like Active Galactic Nuclei and Gamma Ray Bursters. In fact, any cosmic source of high-energy charged particles and gamma rays will inevitably also produce neutrinos. Unlike photons and charged particles neutrinos are not affected by the gas, the dust and the magnetic fields they pass through on their journey, due to their small interaction probability. However, for the same reason, they are hard to detect, requiring very large detector volumes (of the order of km3), placed deep under ice or water. These telescopes can detect the interaction products of neutrinos in ice or water through the Cherenkov Effect, whilst the overburden water or ice protect them from most of the backgrounds caused by the inescapable rain of cosmic rays upon the atmosphere. The neutrino telescopes are accurate trackers of neutrino messengers from Cosmos able to observe and study cataclysmic phenomena occurring in the Galactic and Extra-Galactic space as well as to discover hidden, active astrophysical objects.

The HELYCON detector has been used as a test bench to design a calibration system for underwater neutrino telescopy. Such a system has been proposed as a Sea Top calibration infrastructure for the future Mediterranean neutrino telescope, KM3NeT.  In parallel, the Data Acquisition Techniques developed for the HELYCON electronics have been evaluated to be used as read out electronics of the currently considered detection units of the KM3NeT.
