Description
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 analyzers and the full pulse of the ESS. The design enables the use of elastic and inelastic
fixed window scans. As a special feature it extends the dynamic range by combined analysis of the
fundamental Bragg reflection and the second order
