get_ion_saturation_current

plasmapy.diagnostics.langmuir.get_ion_saturation_current(probe_characteristic)

Implement the simplest but crudest method for obtaining an estimate of the ion saturation current from the probe characteristic.

Parameters:probe_characteristic (Characteristic) – The probe characteristic that is being analyzed. Returns:I_is – Estimate of the ion saturation current in units convertible to A. Return type:Quantity

Notes

The method implemented in this function takes the ion saturation current as the smallest probe current in the characteristic. This assumes the bias range in the ion region is sufficiently negative for the ion current to saturate.
