Back-diffusion of electrons and its process modelling
Marija Radmilović-Rađenović
Back-diffusion of electrons to the cathode has been analyzed by the Monte Carlo simulation. We have studied the influence of different aspects of back-diffusion modelling in particular, with the primary aim to find out a minimum set of parameters necessary for the simulation of the back-diffusion effect. The results are presented in a form that permits reasonable estimation of the back-diffusion to be expected in experimental situations. The obtained results are useful in modelling plasma displays, low pressure gas breakdown and nuclear particle detectors.
Key words: back-diffusion, energy
distribution, angular distribution, Monte Carlo simulation. |
