The JAEA-AMS-TONO system has not only been continuously in operation for the routine measurement of C, but also has been made available for Be- and Al-AMSs in recent years. The C-AMS has applied to research into deep underground environments, and has also been used by researchers from universities and other institutes under the common-use facility program. Development of Be-AMS had been implemented for the past few years. After series of optimization of system/measurement conditions and test measurements, we completed the development last year and have started routine measurement from this year. Since this March, we have started development of Al-AMS. The system set up for Al-AMS and test measurement was carried out. Ratios of Al/Al in standard samples were almost corresponding to reference values. The development has so far done well and routine measurements of the Al-AMS will be started in near future.
