A low energy broad beam multipole ion source has been successfully dev
eloped at the Southwestem Institute of Physics, which can be used for
both sputtering deposition and direct ion beam deposition. The extract
ed A(r)+ beam current is 30-250 mA at a beam energy of 200-6000 eV. It
has been used for sputtering deposition at the three beam synchronous
ly mixing machine in Dalian University of Technology.
