The scheme of an internal injection of Au atoms into the working space of the ''Krion-2'' electron string ion source (ESIS) was applied and tested. In this scheme Au atoms are evaporated from the thin tungsten wire surface in vicinity of the source electron string. Ion beams with charge states up to Au{sup 51+} were produced. Ion-ion cooling with use of C and O coolant ions was studied. It allowed increasing of the Au{sup 51+} ion yield by a factor of 2. Ions of Kr up to charge state 28+ were also produced in the source. Electron strings were first formed with injection electron energy up to 6 keV. Methods to increase the ESIS ion output are discussed.
