Abstract:
We have investigated the performance of a cold and a thermal neutron powder diffractometer installed at at long-pulsed source with the use of Monte Carlo ray tracing simulations. We show that the cold powder diffractometer will be a very powerful instrument when a relaxed resolution can be accepted – e.g. for magnetic studies. A comparison between a thermal powder diffractometer with and without Wavelength Frame Multiplication (WFM) show that the WFM technique can be used to achieve shorter instrument length without losing flux. The thermal powder diffractometer will be competitive with the existing high resolution powder diffractometers.
