  The SoLid experiment aims to resolve the reactor anti neutrino anomaly by
searching for short baseline neutrino oscillations. The experiment makes use of
a novel detector technology based on the combination of 5cm x 5cm x 5cm PVT
cubes and 6 LiF:ZnS screens. This technology provides an improvement for the
background rejection capabilities, the neutron identification and the
localization of the inverse beta decay compared to the standard liquid
scintillators + Gd detectors. These proceedings discuss the construction and
commissioning of the first module installed at the BR2 research reactor in
SCK-CEN, Mol, Belgium. Radioactive sources are used to study the light
attenuation and to calibrate the energy response of the detector.
