Application of numerical methods and computational simulations to plasma-sheath conditions for virtual cathodes under high emmision currents : master thesisKrek, Janez, 1972-Plašč plazme volumsko predstavlja majhen, vendar zelo pomemben, del industrijskih, laboratorijskih ali fuzijskih plazemskih naprav. V plašču se dogajajo velike časovne in prostorske spremembe ... parametrov plazme (električno polje, potenciali, itd.). V magistrskem delu je za modeliranje plazemskega plašča in pogojev nastanka virtualne katode uporabljen model planarne diode. Predstavljeni so teoretični (fizikalni) modeli popisa nastanka virtualne katode ter primeri simulacije njenega nastanka s preizkušenim simulacijskim programom XOOPIC v 2D prostoru. V XOOPIC, ki 2D Particle-In-Cell (PIC) koda, so bile za ugotovljene pomanjkljivosti dograjene izboljšave. Kot nov prispevek je bila dograjeno določanje gradientov električnih polj. Pomanjkljivosti odpravlja predstavljena brezmrežna metoda treecode (TC), ki je bila dodana v obstoječo 1D simulacijsko kodo. Predstavljeni so rezultati simulacij s PIC in TC programi kot tudi primerjava rezultatov obeh simulacijskih programov.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
