Neutron speed echo add-on to TAS: an increase in energy resolution without the use of polarized neutrons

The use of neutron speed echo technique in a low-resolution mode in the combination with triple-axis spectrometers (TAS) allows for a significant improvement of the energy resolution of TAS, however, without the use of polarized neutrons. This fact opens new possibilities for the study of magnetic phenomena in solids (where the neutron spin echo method is principally not applicable because of the neutron precession in the sample), especially by combining polarization analysis with high-resolution spectroscopy.
