Advanced Detector Centre

The Advanced Detector Centre provides solutions for photon detection through development focused projects. We aim to increase industry funding, build new links with industry and external organisations and enhance the alignment of research at Sheffield with industrial needs by translating fundamental research into prototypes and instrumentations.
