Perspectives for spectroscopy at the future European Spallation Source — •Nicolò Violini, Jörg Voigt, Thomas Brückel, Earl Babcock, and Zahir Salhi — Jülich Centre for Neutron Science, JCNS, Forschungszentrum Jülich GmbH, ESS Design Update Program - Germany, D-52425 Jülich Germany
Within the ESS Design Update Program funded by the German Federal ministry of Education and Research, we investigate the performance of a multispectral time-of-flight spectrometer at the long pulse source of the ESS, which promises the applicability to a wide manifold of scientific activities of research: strongly correlated electron materials, disordered systems, functional materials, magnetism, soft-matter and biophysics. The concept makes use of a pin-hole 2.5x4.5cm2 at 6m from the moderator that helps to reduce the background. A powerful double elliptic guide system is able to transport neutron brilliance to a small sample size 1x3cm2, with a brilliance transfer approaching 1. The chopper system contains fast choppers in the focal points of the ellipses providing unprecedented resolution or intensity depending on the request of the experiment. In combination with the band-width choppers and pulse suppression choppers, the system is perfectly adapted to the requirements of the novel repetition rate multiplication method. The use of polarization analysis for this instrument class is under investigation and its implications will be discussed during the talk.
