One of the big detectors which record these collisions, they didn't think there was technology that could withstand the radiation that would be created in the LHC, so there was basically a lump of lead in the middle of this object with some detectors around the outside, but subsequently we have developed technology.
Eén van de detectoren die deze botsingen waarnemen -- men dacht dat technologie die de straling in de LHC zou kunnen weerstaan niet bestond -- dit object bevatte dus een klomp lood binnenin met wat detectoren er rondom, maar daarna hebben we de technologie ontwikkeld.
