Cross-sectional views of the discussed setups showing the shape of the effective precession regions. (a) An NSE spectrometer with homogeneous magnetic field integrals shown as flat precession field area boundaries. (b) Linear SESANS with shifters generating a gradient in the magnetic field integral along the x direction, as illustrated by the inclined front and end faces of the precession field areas. This setup works with longitudinal or transverse precession fields. (c) A SESANS instrument with radial shifters, which generate a radial gradient of the magnetic field integral gradient with rotational symmetry about the optical axis of the instrument. This is illustrated by the conical front and end faces of the precession field area boundaries. |
