Abstract

Construction of a new facility for AMS has commenced at the tandem accelerator center based on a 12UD Pelletron tandem. A “di-molecular pilot beam” method is used for AMS measurements without any modification to the existing tandem system. The absolute 26Al/27Al ratio is measured with two sets of standard 26Al samples to confirm the di-molecular pilot beam concept.

    However, about half the operational beam time in recent years was used for accelerator mass spectrometry (AMS). The Tsukuba AMS system on the 12UD Pelletron tandem accelerator was developed in 1993 [3], and principally used for 26Al and 36Cl AMS. We measured more than 500 samples per year, particularly 36Cl AMS for earth and environmental science (e.g., ice cores, meteorites, and environmental, hydrological, and geological samples) and also nuclear assessment research (radioisotope tracer, radiation safety, etc.) [4].

    Fig. 1 shows the outline of the Tsukuba 129I-AMS system. As we have reported previously [5–7], instead of a generating voltage meter (GVM) feedback method to stabilize the terminal voltage, a molecular pilot beam feedback method was introduced because the GVM system would not gives us sufficient acceleration voltage accuracy. The voltage of the tandem accelerator can be kept within 0.1% accuracy under the pilot beam method.
