  In RIKEN Nishina accelerator center, the experiment on the super-heavy element (Z=113) search has been being carried out since 2003. The RIKEN heavy-ion linac is supplying a heavy-ion beam of 70Zn with energies around 5MeV/nucleon. The beam intensities are required more than 1 particle maicro amper on the target. Very long-term and stable operations are intrinsic for this kind of experiments. So far two events for Z=113 have been found during a net irradiation time of 10345 hours (431 days) with a total dose 1.1 x 1020 (12.8 mg). Heavy operation of the linac will be reported.
