`TransmissionAmplitude`

class nexus.TransmissionAmplitude(experiment, sample, energy, angles, id='')

Bases: Measurement

Constructor for the TransmissionAmplitude class. Calculates the amplitude of the experiment for one sample whose incidence angle is changed in grazing-incidence transmission geometry. No beam profile correction is applied.

Parameters:

id (string) – User identifier.
experiment (Experiment) – Experiment.
sample (GrazingSample) –
Sample of the Experiment whose angle is changed.

Changed in version 2.0.0: changed from old Sample class to GrazingSample.
energy (float) – X-ray energy in eV.
angles (list) – List of the angles.

id
