Abstract
The triple axis spectrometer (TAS) has long been the mainstay for measuring excitations in single crystal samples. In a recent paper Dorner has claimed that the TAS would be the instrument of choice for such measurements at any future high flux spallation neutron source. However, a comparison of the operational characteristics of a TAS and those of direct and indirect geometry time of flight spectrometers for this type of measurement at a pulsed source shows that the TAS would not in fact be a particularly competitive instrument for this purpose.File in questo prodotto:
