Universal Beam Monitor Detector (UniBeaM)

The universal beam monitor (UniBEaM) detector is based on the collection of light produced by scintillation inside Ce and Sb doped silica fibres passing through the beam. This detector is suitable to monitor both pulsed and continuous beams and can measure beams ranging from fractions of pA to about 20 μA. These developments attracted the interest of industry and the UniBEaM is now commercialised under license by the Canadian company D-Pace. The UniBEaM detector was adopted by several laboratories, including the Swiss Federal Office of Metrology (METAS), the Australian National University Department of Nuclear Physics, the University of Michigan Ion Beam Laboratory, and the Los Alamos National Laboratory.
