Important

The Analysis and Diagnostic framework is in active development at the moment. For the foreseeable future, the API will be in continuous flux as functionality is added and modified. To follow the package development please visit our GitHub Project ( https://github.com/PlasmaPy/PlasmaPy/projects/19 ) and comment on any of the relevant issues and/or pull requests.

Swept Langmuir Analysis Module

Subpackage containing routines for analyzing swept Langmuir probe traces.

Example Notebooks

Swept Langmuir Analysis: Floating Potential

API

Sub-Packages & Modules

floating_potential	Functionality for determining the floating potential of a Langmuir sweep.
helpers	Helper functions for analyzing swept Langmuir traces.
ion_saturation_current	Functionality for determining the ion-saturation current of a Langmuir sweep.

Classes

ISatExtras(rsq, fitted_func, fitted_indices)	Create a tuple containing the extra parameters calculated by find_ion_saturation_current.
VFExtras(vf_err, rsq, fitted_func, islands, ...)	Create a tuple containing the extra parameters calculated by find_floating_potential.

Functions

check_sweep(voltage, current[, strip_units])	Function for checking that the voltage and current arrays are properly formatted for analysis by plasmapy.analysis.swept_langmuir.
find_floating_potential(voltage, current[, ...])	Determines the floating potential (\(V_f\)) for a given current-voltage (IV) curve obtained from a swept Langmuir probe.
find_ion_saturation_current(voltage, current, *)	Determines the ion-saturation current (\(I_{sat}\)) for a given current-voltage (IV) curve obtained from a swept Langmuir probe.

Aliases

PlasmaPy provides aliases of the most common plasma functionality for user convenience. Aliases in PlasmaPy are denoted with a trailing underscore (e.g., alias_). For further details, please refer to the contributor guide’s section on aliases.

find_isat_(voltage, current, *[, fit_type, ...])	Alias to find_ion_saturation_current().
find_vf_(voltage, current[, threshold, ...])	Alias to find_floating_potential().
