Abstract

Epithermal neutrons are unique probes for deep inelastic neutron scattering (DINS) at high-energy and high-momentum transfer and inelastic neutron scattering (INS) at high-energy and low-wave vector transfers. In the latter case the kinematic range has recently been revisited given that the high values of initial and final wave vectors achievable in a scattering process coupled to small scattering angles allow to access a so far unexplored region in q,ω, i.e ω>1 eV and q<10 Å−1. In order to exploit DINS and INS in the high-energy and low-momentum range, a very low angle detector (VLAD) bank will be delivered within the e.VERDI Project together with a novel bank at intermediate scattering angles. The former will provide a new tool for investigating high-energy excitations in magnetic systems and semiconductors. The VLAD bank will be constructed following the concept of a resonance detector (RD) spectrometer, recently revised for DINS experiments in the range 1–100 eV.This is a more promising approach in terms of efficiency and signal-to-noise ratio compared to standard neutron counting techniques at eV energies. Results from two devices, cadmium zinc telluride (CZT) solid-state detectors and YAlO3 perovskite (YAP) scintillators used in RD configurations, will be presented.
