Scientific software description
The package is intended for quick calculation of the electron energy distribution function and correspondent collisional rate coefficients in the gas-discharge or electron beam formed plasma under arbitrary non-stationary conditions. Calculations are based on the Boltzmann equation. Original, effective and quick numerical methods are developed.
A physical model takes into account the following processes: heating of electrons by electric field, high-voltage beam heating of electrons and creation of the secondary electrons, electron-electron collisions, elastic, inelastic and superelastic electron-atomic collisions, recombination, attachment and a number of other processes. Each of them may be turned on/off by means of a start menu.
Arbitrary set of active particle types may be taken into consideration. The distribution function may be calculated in accordance with the kinetics of population densities, determined basing on the real rate coefficients.
The package may be used
for the electron distribution function and electron transport coefficients
analysis in any physical situation - independently, or as a subroutine
for other plasma simulation program (see NIKIN-B
package description). The package provides useful graphical representation
of the distribution function time evolution.
Scientific software discription
The package is intended for a quick calculation of the electron energy distribution function, formed as a result of energy degradation process, initiated by electron beam or other high-speed particle beam propagation through a gas mixture.
The energy distribution function is derived from so called "Degradation Equation". A new effective and reliable numerical method is developed to solve this equation. PC run time in case of electron degradation in argon is about 1 sec only for IBM PC /486, with exact particle number and total energy conservation.
The program may be used
for determination and investigation of any beam formed plasma characteristics
- independently, or as a subroutine.
