The SCONE detector is a new type of counter developed and built at LMCE. It is inspired by detectors originally designed for neutrino detection. However, it stands out from all its predecessors used in nuclear physics in that it is made of plastic scintillator rather than liquid organic scintillator. Instead of being a large liquid-filled tank (typically around 1 m$^{3}$), it is composed of nearly a thousand scintillating plastic bars. These bars are grouped into assemblies—most of which consist of 36 bars—that act as independent detectors. This design makes SCONE particularly interesting, as it can perform the same kind of measurements as previous detectors (precise neutron counting and $\gamma$-ray calorimetry), but with a novel capability: $\gamma$-ray counting. It is currently used to study various types of reactions, such as neutron production reactions, and both induced and spontaneous fission. This new instrument has been the subject of a publication in a specialized journal dedicated to nuclear and particle physics instrumentation [1].
