HALO development:
The HALO supernova neutrino detector in SNOLAB is unique among neutrino detectors in that it is primarily sensitive to electron-type neutrinos, rather than electron-type antineutrinos. As such, it has an important role to play in understanding the neutrino flavour content of the neutrino burst from the next galactic core-collapse supernova.
The period 2013-2018 had several highlights for HALO:
- The completion of the construction of the HALO detector and its water shielding
- The calibration of the detector with a neutron source inserted at multiple locations within the lead matrix
- HALO joining the international SuperNova Early Warning System (SNEWS) in October 2015
