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
• 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
