get_electron_temperature

plasmapy.diagnostics.langmuir.get_electron_temperature(exponential_section, bimaxwellian=False, visualize=False, return_fit=False, return_hot_fraction=False)

Obtain the Maxwellian or bi-Maxwellian electron temperature using the exponential fit method.

Parameters:
  • probe_characteristic (Characteristic) – The probe characteristic that is being analyzed.
  • bimaxwellian (bool, optional) – If True the exponential section will be fit assuming bi-Maxwellian electron populations, as opposed to Maxwellian. Default is False.
  • visualize (bool, optional) – If True a plot of the exponential fit is shown. Default is False.
  • return_fit (bool, optional) – If True the parameters of the fit will be returned in addition to the electron temperature. Default is False.
  • return_hot_fraction (float, optional) – If True the total fraction of hot electrons will be returned if the population is bi-Maxwellian. Default is False.
Returns:

T_e – The estimated electron temperature in eV. In case of a bi-Maxwellian plasma an array containing two Quantities is returned.
Return type:

Quantity, (ndarray)

Notes

The exponential section of the probe characteristic should be a straight line if the plasma electrons are fully Maxwellian, or exhibit a knee in a bi-Maxwellian case. The slope is inversely proportional to the temperature of the respective electron population.
