$A method for detailed simulations of neutron diffraction from ... - ESRF$

Main required improvements The main expected improvements concern the detection efficiency and the determination of the polarization by the detector itself. 16
Nuclear scattering Project (Former BL) Application UPBL03: NRS (ID18) Nuclear scattering, nuclear diffraction Aim of the detection system The aim of the detection system is to count with very high time resolution the photons produced by the decay of nuclear excited states (delay) after the exciting pulse (prompt) in order to measure several nuclear scattering processes (nuclear forward scattering, nuclear small angle scattering, nuclear Bragg diffraction). Highly monochromatic, time structured beam Nuclear Inelastic Scattering Sample Operating conditions and specifications Energy range: The energy ranges from 6 to 100 keV, with a particular emphasis at 14 keV (iron resonance). Time scale considerations: The studied phenomena happen in a time scale of a few hundred nanoseconds, thus the detector must provide a time resolution better than the ns. For some isotopes, the lifetime of the nuclear excited state is even shorter and a 100 ps time resolution can be necessary. Even more crucial than the time resolution is the ability of the detector to be ready to count few photons from the “delayed counts” “immediately” after the exposition of the sample to the high photon flux of the “prompt pulse” (typically after less than 10 ns). Energy resolution: Energy resolution is not needed. 17 Nuclear Forward Scattering
