For the RIKEN radio isotope factory (RIBF) project, we produced the multicharged uranium beam with two methods. To produce lower charge state U ion beams (14+-20+) we used the UF{sub 6} gas as an ionized gas. The typical beam intensity of U{sup 14+-20+} was 2-1 particle {mu}A at the extraction voltage of 14 kV. To produce higher charge state U ion beam (U{sup 35+}), we chose the sputtering method. The beam intensity was 70 particle nA at the extraction voltage of 5.4 kV. Using this method, we successfully produced multicharged U beam continuously for one month without break for RIBF commissioning.
