ess.freia.conversions.time_at_shutter#

ess.freia.conversions.time_at_shutter(time_at_detector, wavelength, L2, sample_position, shutter_position)[source]#

Estimate the time the event passed the shutter position.

Parameters:

  • time_at_detector (Variable) – Detector arrival as float64 seconds since the Unix epoch.

  • wavelength (Variable) – Reconstructed neutron wavelengths.

  • L2 (Variable) – Sample-to-detector flight paths.

  • sample_position (Variable) – Sample position in global coordinates.

  • shutter_position (Variable) – Fixed shutter position in the same global frame as the sample.

Returns:

Variable – Time the neutron passed the shutter, as float64 seconds since the Unix epoch.
