Accurate measurements of the emittance directly at the exit of the Ion source allows to minimize beam losses. Issues and difficulties with measuring of a heavy ion beam emittance at the exit of the electron-string source of multiply charged ions KRION-6T are discussed. The measurement using simulation by three profilometers metod is odserved and analyzed. ER -
