Abstract
The results of a systematic investigation of charge exchange in Na or Mg vapours are described together with applications to the production and acceleration of negative heavy ion beams in a tandem accelerator. μA intensities of 20 keV beams.of Li-, Be-, B-, C-, O-, Na-, Al-, Si-, Cl-, Ca-, Fe-, and Au- have been obtained on test bench by charge exchange in Na, Mg, or K vapour of positive beams extracted from standard, universal ion sources. The measured emittance values of these beams are low compared to existing, universal negative sources. μA beams of Li-, Be-, B-, and Fe- have been injected and accelerated with good transmission in our EN tandem acceleratorKeywords
