EEDF is a user-friendly program for the numerical solution of Boltzmann equation for the Electron Energy Distribution Function in low-ionized plasma in an electric field. It is used for calculations of electron transport and kinetic coefficients in gas mixtures.

The reference to EEDF program should be given as follows

The EEDF Access System

The EEDF Access System provides an easy, MENU-driven way to access the Data Bank and programs. Using the MENU-system one can do the following operations:

  • Look through the list of species included in Data bank
  • Choose the components of gas mixture
  • Set up the concentrations of components and the populations of excited states
  • Look through the list of processes for chosen species
  • Set up the parameters of gas mixture: temperature, pressure, electron concentration
  • Choose the electric field type
    • Steady state
    • Radio Frequency
    • Crossed electric and magnetic fiels
  • Set up the values of field parameters
  • Set up some mathematical parameters of program
  • Set up the names and location of output files
  • Choose the format of output text file
  • Look through the summary of chosen parameters
  • Start Boltzmann Equation Solver

Result Viewing program


  • Look through the results of calculation in text and graph modes
  • Save images in bmp format
  • Export of plotted data to text format file

calculated parameters
