The SoLid experiment has been conceived to give an unambiguous response to the hypothesis of a light sterile neutrino as the origin of the Reactor Antineutrino Anomaly. To this end, SoLid is searching for an oscillation pattern at short baselines (6-9 m) in the energy spectrum of the antineutrinos emitted by the SCK-CEN BR2 reactor in Belgium. The detector uses a novel technology, combining PVT (cubes of 5x5x5 cm3) and 6LiF:ZnS scintillators. It is highly segmented, and it is read out by a network of wavelength shifting fibers and SiPMs. The fine segmentation and the hybrid technology of the detector allows the clear identification of the neutrino signals, reducing significantly backgrounds. Thus, a high experimental sensitivity can be achieved. In this seminar I will present the results of the calibration during the construction and I will discuss the status of SoLid.
