Cyclotron use in FY 2012, was 2243.5 hours beam time. Among them, the use time of Bio technology and Medical application relationship most, I occupy the time spent for the Quarter of the total. Use offer to the outside utilization was 17%. Use the number of days in Electrostatic Accelerators was 490 days. Among them, Basic technology is accounted for using the percentage of 46%, but the use of irradiation Reactor materials and irradiation of Material for space even more, I accounted for 18 percent utilization rate, respectively, of 15%. Use offer to the outside utilization was 8%.

Fiscal year 2011 was significantly influenced by the East Japan Great Earthquake (March 11, 2011). The operation of the TIARA facility which was being planned from April started from the middle of May. Lost beam-time of the experiment due to the great earthquake was compensated with operations on Saturday biweekly. And it was obliged to re-examine the operation plan during the period of electric power reduction in July, August, and September. The demanded reduction rate of electric power in daytime for summer season was 15% as compared with 2010. The limited value in daytime was 3,600 kW. Therefore, the experiment in daytime was conducted with light ions (H, D with $$<$$ 20 MeV) only by the AVF Cyclotron. As mentioned above, the electric power in the daytime of summer did not exceed 3,200 kW. Moreover, the beam time as an ordinary year was secured.

Usage situation of TIARA facility is reported. At 2012 fiscal year, TIARA facility was operated as planned without large external factors(Large earthquake, Power reduction requests, etc.). At trends in research field between 1991-2012, challenges of medical and biotechnology is increased and the using ratio of cyclotron is highest in the research field. At the electrostatic accelerators, the using ratio of fundamental technology development has increasing significantly in these 20 years. In addition, external user number is stable 800 or so people in these four years.
