The SoLid antineutrino detector: construction and commissioning with cosmic ray muons

The SoLid experiment, located at the BR2 reactor at SCK CEN, is designed to resolve the reactor antineutrino anomaly, a result clearly in tension with the existing framework of three families of neutrinos oscillating into each other. 
The approach used by SoLid consists of a novel technique to detect reactor anti-neutrinos via the inverse beta decay interactions (IBD), combining 5x5x5 cm3 PVT scintillator cubes equipped with 6LiF:ZnS(Ag) neutron sensitive screens.

The aim of this PhD was twofold. On the one hand a lot of construction work was performed within the SoLid collaboration on both the SubModule 1 prototype and the full-scale detector, Phase 1. Assistance was given in the initial commissioning of the detectors’ sub-parts and installation of both detectors at the BR2 reactor at the SCK CEN in Mol, Belgium. On the other hand, this PhD focuses on the commissioning of both detectors with cosmic ray muons. A cosmic ray simulation package, CosmicGen, was developed and validated with the use of SubModule 1 data. An initial muon study was performed on the Phase 1 December 2017 data, thereby providing understanding of the particle identification, timing and stability of the Phase 1 detector. The initial steps towards an efficient muon veto were taken and it was shown that the detector is capable of identifying prompt-delayed signals.
