- plasmapy.diagnostics.langmuir.get_plasma_potential(probe_characteristic, return_arg=False)
Implement the simplest but crudest method for obtaining an estimate of the plasma potential from the probe characteristic.
V_P – Estimate of the plasma potential in units convertible to V.
- Return type
The method used in the function takes the maximum gradient of the probe current as the ‘knee’ of the transition from exponential increase into the electron the saturation region.
