Production of rare earths ion beams in arc discharge ion source using their oxides

Abstract

Production of rare earth's ions from using their oxides and carbon tetrachloride (CCl 4) vapor is described. Mechanism of internal chemical synthesis of rare earth's chlorides is proposed. Working characteristics like dependences of ion currents on discharge and filament current, magnetic flux density as well as CCl 4 flux are presented and discussed in order to find optimal working parameters. The separated currents of 18 A, 5 A, 3 A and 12 A were obtained for Eu + , Gd + , Ho + and Pr + , respectively. Streszczenie. W atykule opisana jest metoda wytwarzania wiązek jonów pierwiastków ziem rzadkich wykorzystująca ich tlenki i pary czterochlorku węgla (CCl 4). Zaproponowano także wyjaśnienie mechanizmu wewnętrznej syntezy chlorków ziem rzadkich. Celem znalezienia optymalnych parametrów pracy rozpatrywanane są charakterystyki robocze źródła, takie jak zależności natężenia prądów jonowych od natężeń prądu wyładowania, grzania katody, indukcji magnetycznej zewnętrznego magnesu jak również nacieku CCl 4. Otrzymano rozseparowane wiązki jonów

New Approach to Non-Volatile Metal Ion Production Using Plasma Ion Source with Internal Evaporator

“…The versatility of that particular kind of ion sources is due to the possibility of tailoring of the internal evaporator, namely size and placement inside the source [44]. It should be also mentioned here that ion source could be feed with chlorine and fluorine containing working gases like CCl 4 , HCCl 3 or CCl 2 F 2 which proved to work well for production of Mo + and Ta + ions [45,46] as well as rare earths' ions using their oxides [47].…”
