SoLid: why and how we search for sterile neutrinos

Although neutrino oscillations were discovered more than 10 years ago, some anomalies, such as the reactor antineutrino anomaly, still remain in the neutrino oscillation data. The existence of a light sterile neutrino could explain these anomalies. The SoLid experiment aims to resolve the inconsistencies in the neutrino oscillation sector and to test the sterile neutrino hypothesis. To be able to perform this sensitive measurement a novel detector technology is used, based on the combination of solid scintillator PVT cubes in combination with $^6$LiF:ZnS screens. Compared to standard liquid scintillators + Gd detectors this technology will allow for a better background rejection capability, neutron identification and localization of the inverse beta decay. During the past 2 years the SoLid collaboration has build 2 prototype detectors and it is now in the process of building a full scale 1.5 ton detector. This poster covers the novel technology used in the SoLid experiment and discusses the improvements made on the design and electronics for the construction of the full SoLid detector.
