  Gamma-ray Spectroscopy with Perfect Crystal Spectrometers
  The ILL operates one of the most intense neutron sources for research in the world. Although primarily used for neutron scattering there exist a long-standing history of gamma ray spectroscopy at the ILL. The availability of well collimated intense neutron beams and in-pile sample irradiation positions allowed to develop quite unique instruments and applications of gamma ray spectroscopy. In a first part I will give a brief overview on ILL’s nuclear physics instrument suite.
  Amongst the operating gamma ray instruments the ultra-high-resolution gamma ray spectrometers GAMS played a particular role due to their outstanding energy resolution and dynamic range. The instruments are based on perfect crystal Laue diffraction of gamma rays yielding an energy resolution down to a few eV at MeV energies. The instruments contributed in the past to many different fields in physics: nuclear structure, metrology, photon matter interaction, crystallography and astrophysics. In a second part the talk will review some highlights from the recent years of operation of these instruments.
  In 2020 the ILL decided to decommission the GAMS spectrometers. Therefore, in the third and last part of the talk I will try to give an outlook in which field the techniques and technology of the GAMS spectrometers could be used in the future. In this respect I will focus mainly on the combination of such devices with a Laser-Compton source for NRF experiments.
