• Effect of permanent magnets on plasma confinement and ion beam generation in a double layer helicon plasma source 

      Varberg, Erik (Master thesis; Mastergradsoppgave, 2016-06-01)
      The work described in this thesis was carried out to investigate how additional permanent magnets (PM) could affect the confinement and ion beam generation in a plasma which expands from a helicon source. PMs added to a plasma source systems has been shown to provide an increased plasma confinement, but is not widely used. This inexpensive and cheap method of using PMs which does not require any ...
