Time-of-flight graph of the neutron paths for neutrons detected at the edge of the detector that have gained energy from phonons. The lower thick line is for the fastest elastically scattered neutron at the start of the chopper pulse and the upper thick line is for the slowest elastically scattered neutron at the end of the chopper pulse. The sample is between 0.25 and 0.31 m from the chopper; the graphs for the fastest and slowest incident neutrons gaining 13.2 meV are shown by the thin lines, and the graphs for the fastest and slowest incident neutrons gaining 4.5 meV are shown by the dashed lines. The dot–dash lines and the dot–dot–dash lines are, respectively, for neutrons gaining more than 13.2 meV or less than 4.2 meV. The vertical dotted lines show the spatial region over which the detector can detect neutrons (t1 = 1494 µs, t2 = 3310 µs, t3 = 3639 µs, t4 = 5508 µs).
