Wide angle neutron spin echo and time-of-flight spectrometer

The cylindrical symmetry of the magnetic field configuration of SPAN enables simultaneous neutron spin echo measurements over the whole range of scattering angles accessible by a spectrometer. The open construction also allows for time-of-flight measurements and the combination of these two techniques leads to a remarkably broad dynamic range of more than four orders of magnitude, which makes SPAN particularly attractive when it comes to studying the dynamics of complex disordered systems like (spin)glasses or polymers.
