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 is 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.
