Performance of a high-current metal vapor vacuum arc ion source

“…Ion sources incorporating the vacuum arc as the plasma production mechanism have been investigated by several authors [6][7][8][9][10][11][12][13][14][15]. The metal vapor vacuum arc (MEVVA) ion source developed at Lawrence Berkeley Laboratory was initially made for the injection of high current beams of metal ions into the Bevalac heavy ion synchrotron for basic nuclear physics research [ 16,17]; more recently the source has also been used for high dose metal ion implantation for purposes including.the formation of buried metal silicide layers [18] and the compositional fine-tuning of high-Tc superconducting thin films [19]. Several different embodiments of the MEVV A ion source have been designed and described [6,15,20,21].…”
