Correction for beam divergence effect in a NRSE spectrometer with high resolution.

A correction for the beam divergence effect in a neutron resonance spin echo (NRSE) spectrometer will be discussed. The new type of device called 'coupling coils' is proposed to change the spin quantization axis for the correction. The feasibility of correction for the vertical divergence has been demonstrated by numerical calculations and Monte Carlo simulations. [ABSTRACT FROM AUTHOR]
