We discuss different concepts to realize crystal analyzer spectrometers at long pulse neutron sources.
For the novel High Current Accelerator driven neutron sources, crystal arrays designed for large ac-
ceptance enable resolutions down to 10 μeV with reasonable detector count rates.
For the ESS we present a concept that might enable neV resolution by using GaAs monochroma-
tors and...
Inelastic neutron scattering measurements are usually (except on Spin Echo), performed by knowing the initial and final energy of each neutron detected. This information is used to obtain the double differential scattering cross section, d$^2$$\sigma$/d$\Omega$d$\omega$, the probability of a scattered neutron being directed in the solid angle between $\Omega$ and $\Omega$+d$\Omega$ having...
We present the instrument concept for KVASIR, a backscattering indirect time-of-flight neutron spectrometer for the European Spallation Source (ESS). KVASIR will probe low lying excitations in single crystals of hard condensed matter. The instrument follows the FARO/SHERPA concept, using mosaic prismatic PG analyzer crystals. KVASIR is simultaneously optimized for high resolution of energy-...
Within this presentation we want to show new developments on sample environment dedicated for TOFTOF. Although we want to show and discuss our planed upgrade program for TOFTOF.
The TOSCA spectrometer is a broadband indirect geometry spectrometer, with a particular sensitivity to and high-resolution in the chemical fingerprint region ħω = 50–200 meV (400–1600 cm−1), making it well suited to the study of molecular vibrations. TOSCA has been operating since 1998 and with a guide upgrade in 2017 providing a significant flux increase. To keep the instrument competitive...
Neutron polarization analysis provides profound additions of knowledge to the field of soft condensed matter research. The ability to separate the coherent and incoherent scattering contributions gives information on spatial correlations and collective motion, and information from single particles, respectively.
In this study, we focus on upgrading the SPHERES (SPectrometer for High Energy...
The National Institute of Standards and Technology (NIST) Center for Neutron Research (NCNR) has been operating a neutron spin echo spectrometer since the later ‘90s. Recently, through a collaboration among the University of Delaware, the University of Maryland and the NCNR with a strong support from the Jülich Center for Neutron Science, the instrument was significantly upgraded using funding...
