Wavelength frame multiplication

Wavelength frame multiplication¶

  • Introduction to Wavelength Frame Multiplication
    • The long ESS pulse
    • So what is WFM anyway?
    • A closer look
      • The ESS pulse shape
      • Using a single WFM chopper
      • Using a pair of optically blind choppers
    • A short example
      • Create a beamline
      • Create some neutrons
      • Wrap the neutron counts and the beamline into a DataArray
      • Stitch the frames
    • References
  • Reducing WFM data
    • Create beamline components
    • Generate some fake data
    • Visualize the beamline’s chopper cascade
    • Discard neutrons that do not make it through the chopper windows
    • Create a realistic Dataset
    • Stitch the frames
    • Convert to wavelength
    • Normalization
    • Comparing to the raw wavelengths
    • Without WFM choppers
    • Working in event mode
