Enhancing the performances of a resonance detector spectrometer for deep inelastic neutron scattering measurements
2012
The possibility is explored to sum up neutron Compton profiles at different scattering angles in deep
inelastic neutron scattering measurements within the Resonance Detector (RD) configuration to
enhance the statistics for a more reliable extraction of the momentum distribution of the constituents
in the target. The RD configuration allows to select the energy of the scattered neutrons up to several
tens of electron Volt, thus accessing energy and wave vector transfers well above 1 eV and 30 ˚A 1,
respectively. In the high-q/o regime, the final state effects could be considered as negligible, as shown
in a series of simulations using a Monte Carlo method with different inverse geometry instrument
setups. The simulations show that it could be possible to conceive an instrument set up where the RD
configuration allows the proper summation of several spectra at different scattering angles, providing a
good separation of the proton recoil signal from that of the heavier atoms, thus avoiding the cell
subtraction by fitting procedure.
