Work on metal vapor vacuum arc (MEVVA) ion source development was init
iated at the Institute of Low Energy Nuclear Physics, Beijing Normal U
niversity, in 1988. MEVVA ion sources I, II, IIA, and III have been de
signed, fabricated, and tested, and an ion implantation facility with
three MEVVA ion sources has been developed and is now undergoing testi
ng. Here the status of the MEVVA ion source research and development p
rogram is described.
