(a) A qualitative sketch depicting the transmission T(λ) and Δλ/λ as a result of the chopper configuration and instrumental setup. (b) A path–time diagram for neutrons moving from the pulse chopper to the detector. The times where the respective choppers are in the closed state are highlighted with a solid grey line along the time axis. Opening times, during which neutrons can pass, are represented by gaps within these lines. λmin is the lowest transmitted wavelength and λmax the highest, and λ1 and λ2 are the lowest and highest wavelengths, respectively, that can pass the chopper array with the full span of the pulse length τ.
