A B S T R A C T Title: Recombination of Ions in Plasma at 50 − 300 K Author: Peter Rubovič Supervisor: Prof. RNDr. Juraj Glosík, DrSc. Abstract: Main part of this doctoral thesis lies in a study of recom- bination of atomic and molecular ions in low temperature plasmatic environment with emphasis on effect of third bodies. Stationary After- glow equipped with Cavity Ring Down Spectrometer and Cryogenic Flowing Afterglow with Langmuir Probe II were used to obtain recom- bination rate coefficients. Electron assisted collisional radiative recom- bination of Ar+ ion was studied in the temperature range of 50−100 K and helium assisted collisional radiative recombination was observed too. Both H+ 3 and its isotopologue D+ 3 were studies in flowing after- glow and spectroscopically in stationary afterglow as well. Binary re- combination rate coefficients and ternary recombination rate coeffi- cients for helium assisted ternary recombination were determined in the temperature range of 50 − 250 K. These coefficients were deter- mined also for pure ortho- and para- nuclear spin configurations of H+ 3 in the temperature range of 80 − 200 K. Keywords: dissociative recombination, collisional radiative recombi- nation, H+ 3 , D+ 3 , Ar+ viii A B S T R A K T Názov práce: Rekombinácia iónov v plazme pri 50 − 300 K Autor: Peter Rubovič Vedúci doktorskej práce: Prof. RNDr. Juraj Glosík, DrSc. Abstrakt: Hlavná čast' tejto doktorskej práce spočíva v štúdiu rekom- binácie atomárnych a moleculárnych iónov v nízkoteplotnom plazma- tickom prostredí s dôrazom na efekt tretích telies. Boli použité metódy stacionárnej dohasínajúcej plazmy s cavity ring down spektrometrom a kryogénnej prúdiacej dohasínajúcej plazmy. Elektrónom asistovaná zrážkovo radiatívne rekombinácia iónov Ar+ bola študovaná v teplot- nom rozsahu 50−100 K, héliom asistovaná zrážkovo radiatívna rekom- binácia bola pozorovaná tiež. Ión H+ 3 a jeho izotopológ D+ 3 boli štu- dované ako v prúdiacej dohasínajúcej plazme, tak aj spektroskopicky v stacionárnej dohasínajúcej plazme. Binárne rekombinačné koeficienty a ternárne rekombinačné koeficienty pre héliom asistovanú ternárnu rekombináciu boli určené v teplotnom rozsahu 50 − 250 K. Tieto koe- ficienty boli stanované aj pre ortho- a para- konfigurácie spinu jadra iónu H+ 3 v teplotnom rosahu 80 − 200 K. Kl'účové slová: disociatívna rekombinácia, zrážkovo radiatívna rekom- binácia, FALP, CRDS, H+ 3 , D+ 3 , Ar+ vii
Keywords: Ar+; collisional radiative recombination; D3+; dissociative recombination; H3+; Ar+; CRDS; D3+; disociatívna rekombinácia; FALP; H3+; zrážkovo radiatívna rekombinácia
