N2 - We built a spin-echo setup for SANS, consisting of precession devices each made up of 2 adiabatic RF flippers. For angle labelling of the neutron beam, the poles of the dipole magnets for these flippers are shaped as parallelograms. SANS in a sample shows up as depolarisation, i.e. a decrease in the amplitude of the spin-echo signal. Spin-echo SANS measurements in two samples are given, showing the difference in particle size distribution. Since adiabatic RF flippers work for the full white spectrum, the method works also on pulsed sources.
