Schematic diagram of neutron flight paths. The dash–dot–dot line is for the shortest wavelength incident neutron (λmin) at the start of the chopper pulse gaining the maximum energy from the phonons in the sample (λmin − Δλmax). The dash–dot line is for the longest wavelength (λmax) at the end of the chopper pulse gaining the minimum energy from phonons in the sample (λmax − Δλmin). |
