Abstract

<p>The 4D Space Access Neutron Spectrometer (4SEASONS) is a high-intensity Fermi-chopper spectrometer. It is intended to provide high counting rate for thermal neutrons with medium resolution (Δ<i>E/E</i><sub>i</sub>~6% at <i>E</i>=0) to efficiently collect weak inelastic signals from novel spin and lattice dynamics especially in high-<i>T</i><sub>c</sub> superconductors and related materials. To achieve this goal, the spectrometer equips advanced instrumental design such as an elliptic-shaped converging neutron guide coated with high-<i>Q</i><sub>c</sub> (<i>m</i>=3–4) supermirror, and long-length (2.5m) <sup>3</sup>He position sensitive detectors (PSDs) arranged cylindrically inside the vacuum scattering chamber. Furthermore, the spectrometer is ready for multi-incident-energy measurements by the repetition rate multiplication method, which greatly improves the measurement efficiency.</p>
