extrapolate_electron_current
(probe_characteristic, fit, bimaxwellian=False, visualize=False)¶ Extrapolate the electron current from the Maxwellian electron temperature obtained in the exponential growth region.
Parameters:  probe_characteristic (Characteristic) – The probe characteristic that is being analyzed.
 fit (ndarray) – Polynomial fit coefficients returned by the electron temperature fit.
 bimaxwellian (bool, optional) – If True the electron current is extrapolated assuming biMaxwellian electron populations, as opposed to Maxwellian. Default is False.
 visualize (bool, optional) – If True a plot of the extracted electron current is shown. Default is False.
Returns: electron_current – The extrapolated electron current characteristic.
Return type: Notes
Assuming the electron population is fully Maxwellian the pure electron current is extrapolated from the fit of the exponential region for the entire bias range.
