Sažetak

The 6 MV tandem electrostatic accelerator at the "Ruđer Bošković" Institute went into operation in 1987. Negative ion source is an essential part of such an accelerator. Negative ion sources installed with tandem accelerator at the "Ruđer Bošković" Institute are duoplasmatron with exchange canal and sputtering ion source (installation in progress). Duoplasmatron is used mostly for production of H⁻ beams. Modification of donor canal, for production of He⁻ ions, is in progress. Tantalum filament is replaced with directly heated lanthanum hexaboride filament. It is expected that the source lifetime of about 100 hours will be increased several times with the addition of that new filament.
