Abstract
The new neutron spin-echo (NSE) spectrometer that recently went into o peration in the guide hall ELLA of the DIDO reactor FRJ-2 in Julich is described. Design consideration and measured performance data are rep orted. The innovation of magnetic decoupling by rigidly coupled compen sation loops yields a number of benefits as ease of operation, stabili ty and immediate access to high scattering angles. A new technical rea lization of the correction elements yields large area coverage and hig h transparency. Together with an area multidetector this results in a highly efficient neutron usage. The operation program allows for ''set -and-run'' operation without tuning increasing again the overall neutr on economy.
