Description

For the first time, a diamond sensor was operated for the characterisation of a high average-intensity $\gamma$-ray beam. Data was collected for $\gamma$-beam energies between 2 and 7 MeV, at the HI$\gamma$S facility of TUNL. The nanosecond-fast resolution of diamond detectors is exploited to distinguish bunches of $\gamma$-rays 16.8 ns apart. It allows a precise direct determination of the time-structure of the $\gamma$-beam. The strong potential of such a detector for precise absolute flux, position and polarisation measurements are exposed. It is thus shown that diamond detectors are a decisive and unique tool for the detailed characterisation of upcoming $\gamma$-sources, such as ELI-NP and HI$\gamma$S-2, which will revolutionise the future of nuclear physics.
