get_floating_potential

plasmapy.diagnostics.langmuir.get_floating_potential(probe_characteristic, return_arg=False)

Implement the simplest but crudest method for obtaining an estimate of the floating potential from the probe characteristic.

Parameters
  • probe_characteristic (Characteristic) – The probe characteristic that is being analyzed.

  • return_arg (bool, optional) – Controls whether or not the argument of the floating potential within the characteristic array should be returned instead of the value of the voltage. Default is False.

Returns

V_F – Estimate of the floating potential in units convertible to V.

Return type

Quantity

Notes

The method used in this function takes the probe current closest to zero Amperes as the floating potential.
