Experiment

Definition of an experiment, structure to setup experimental parameters and measurements in STRATAGem.

stratagemtools.experiment.LINE_KA = 0

X-ray line \(\text{K}\alpha\)

stratagemtools.experiment.LINE_KB = 1

X-ray line \(\text{K}\beta\)

stratagemtools.experiment.LINE_LA = 2

X-ray line \(\text{L}\alpha\)

stratagemtools.experiment.LINE_LB = 3

X-ray line \(\text{L}\beta\)

stratagemtools.experiment.LINE_MA = 4

X-ray line \(\text{M}\alpha\)

stratagemtools.experiment.LINE_MB = 5

X-ray line \(\text{M}\beta\)

class stratagemtools.experiment.Experiment(z, line, energy_eV, kratio=0.0, standard='', analyzed=True)

Object to store experimental parameters and measurements. Once created an experiment object is immutable.

Parameters:

• z (int) – atomic number
• line (int) –

  X-ray characteristic line, either

  • LINE_KA
  • LINE_KB
  • LINE_LA
  • LINE_LB
  • LINE_MA
  • LINE_MB

  Note that no other X-ray lines are supported.

• energy_eV (float) – beam energy (in eV)
• kratio (float) – measured k-ratio (optional)
• standard –

  three options

  • empty string for pure standard (e.g. Fe)
  • standard name which correspond to the filename of the standard saved in the standard directory (see Stratagem.standard_directory)
  • a Sample
• analyzed (bool) – whether to use this experiment in the calculations

is_analyzed()

Whether to use this experiment in the calculations.

z

Returns the atomic number.

line

Returns the x-ray characteristic line.

energy_eV

Return the beam energy (in eV).

kratio

Returns the measured k-ratio or 0.0 if no k-ratio was measured.

standard

REturns the standard.
