The CAMEA ESS neutron spectrometer is designed to achieve a high detection efficiency in
the horizontal scattering plane, and to maximize the use of the long pulse European
Spallation Source. It is an indirect geometry time-of-flight spectrometer that uses crystal
analysers to determine the final energy of neutrons scattered from the sample. Unlike other
indirect geometry spectrometers CAMEA will use ten concentric arcs of analysers to analyse
scattered neutrons at ten different final energies, which can be increased to 30 final energies …

The CAMEA ESS neutron spectrometer is designed to achieve a high detection efficiency in the horizontal scattering plane, and to maximize the use of the long pulse European Spallation Source. It is an indirect geometry time-of-flight spectrometer that uses crystal analysers to determine the final energy of neutrons scattered from the sample. Unlike other indirect geometry spectrometers CAMEA will use ten concentric arcs of analysers to analyse scattered neutrons at ten different final energies, which can be increased to 30 final energies by use of prismatic analysis. In this report we will outline the CAMEA instrument concept, the large performance gain, and the potential scientific advancements that can be made with this instrument.
