Cíle projektu: Krátké shrnutí: Cílem projektu jsou odhady radiálního transportu plazmatu indukovaného radiofrekvenčními (RF) vlnami a výpočty profilu hustoty plazmatu vytvářejícího se v důsledku působení radiální difuse a ponderomotivních sil RF vln. Kombinace různých módů RF pole by měla dovolit modelování profilu plazmatu, což by bylo důležité pro plazmové zdroje s helikonovými vlnami používané v plazmových technologiích, kde by patrně bylo možné profil plazmatu modelovat od dutého až po výrazně centrovaný k ose plazmového válce. Rovněž by mělo být spočítáno radiální elektrické pole indukované RF vlnami v různých experimentech, spolu s poloidální a toroidální rotací plazmatu. Stacionární elektrická pole mají důležitou roli v plazmovém leptání a při vytváření H-módůs lepším udržením plazmatu v tokomacích.
Dosažené výsledky: Byly vyvinuty teoretické modely a odpovídající počítačové programy popisující radiální transport plazmatu indukovaný radiofrekvenčními poli. Projekt tak přispěl k přesnějšímu srovnání teoretického modelu s experimentem. Charakteristika výsledků uvedená v
