Figure 1
A time–distance diagram for the new chopper of KWS-2 for LD = 1.6 m and λi = 7 Å (bottom), and the neutron intensity recorded on the detector in TOF mode for two bursts produced by the chopper (top). The path of the elastically scattered neutrons (red and blue lines) is shown along with that of the inelastically scattered neutrons (green line) for the sample with λs = 1 Å. The meaning of different line types and colours is discussed within the main text. |
