Simulated LIBS

SimulatedLIBS provides simple Python class to simulate LIBS spectra with NIST LIBS Database interface.

Project created for B.Eng. thesis:

Installation

pip install SimulatedLIBS

Import

from SimulatedLIBS import simulation

Example

Parameters:

• Te - electron temperature [eV]
• Ne - electron density [cm^-3]
• elements - list of elements
• percentages - list of elements concentrations
• resoulution
• wavelength range: low_w, upper_w
• maximal ion charge: max_ion_charge

libs = simulation.SimulatedLIBS(Te=1.0, Ne=10**17, elements=['W','H','Be'],percentages=[50,25,25],
                                resolution=1000,low_w=200,upper_w=1000,max_ion_charge=3)

Plot

libs.plot(color='blue', title='W Be H composition')

Save to file

libs.save_to_csv('filename.csv')

Interpolated spectrum

SimulatedLIBS interpolates retrieved data from NIST with cubic splines

libs.get_interpolated_spectrum()

Raw spectrum

Raw retrieved data from NIST

libs.get_raw_spectrum()
