  A novel design for a compact gamma-ray spectrometer is presented. The
proposed system allows for spectroscopy of high-flux multi-MeV gamma-ray beams
with MeV energy resolution in a compact design. In its basic configuration, the
spectrometer exploits conversion of gamma-rays into electrons via Compton
scattering in a low-Z material. The scattered electron population is then
spectrally resolved using a magnetic spectrometer. The detector is shown to be
effective for gamma-ray energies between 3 and 20MeV. The main properties of
the spectrometer are confirmed by Monte-Carlo simulations.
