The Helium and Lead Observatory (HALO) is a dedicated supernova detector constructed in the underground facilities at SNOLAB in Sudbury, Canada. It is designed to detect neutrinos from a supernova within the Milky Way galaxy using lead blocks and 3He neutron detectors. Analysis of supernova neutrino events can produce new discoveries in astrophysics and fundamental particle physics. HALO will be a...
The recent development of smart sensors connected through a network is enabling new types of scientific experiments of unprecedented scale at extreme locations. One such experiment is the IceCube neutrino observatory being completed at the geographical South Pole. IceCube's main scientific goals are to detect astrophysical sources of high-energy neutrinos and solve the mystery of the origin of cosmic...
The use of time over threshold (ToT) digitization techniques for the treatment of the output signals of the photomultiplier tubes (PMTs) of the KM3NeT detector is under consideration by the KM3NeT consortium. In this technique the leading and trailing edge of the signal above a certain threshold are time stamped and the corresponding times are sent to the onshore acquisition system. More information...
Acoustic particle detection is a promising approach for the investigation of ultra-high energy neutrinos. This method utilises the effect that a detectable pressure pulse is generated by the particle shower produced in a neutrino interaction in water at very high energies. The AMADEUS (ANTARES modules for acoustic detection under the sea) system is designed to perform tests of detection techniques...
Over the past two years, data have been collected at an array of hydrophones in a search for acoustic signatures of ultra-high energy neutrinos from space. The Study of Acoustic Ultra-high energy Neutrino Detection (SAUND) is a first step towards developing a novel detection method for one of the outstanding problems of both particle physics and astrophysics. The project has produced the first measurement...
