THE PRODUCTION OF IONS OF SOLIDS FROM THE PIG SOURCE WITH AN ADDITIONAL ANODE

In this paper we report the results of production of ions of solids fr om the PIG source with an additional anode and solid material feed by cathode sputtering. The investigations were performed at the test benc h and at the U-400 cyclotron. Two versions of the ion source with diff erent dispositions of the sputtering electrode were studied. In the fi rst version the sputtering electrode is introduced into the discharge chamber through the wall opposite to the emission slit, the second ver sion has lateral disposition of the sputtering electrode. The influenc e of the potential of an additional anode on the total extracted curre nt and charge state distribution was studied at the test bench for bot h versions, The results of the test of the ion source with lateral dis position of the sputtering electrode at the U-400 cyclotron are report ed.
