Developing AMS measurement of 59Ni at CIAE

    Corresponding author: HE Ming,

Abstract: Accelerator mass spectrometry (AMS) measurement of 59Ni has been established at CIAE with the HI-13 tandem accelerator and the recently developed ΔE-Q3D detection system. 59Ni standard and commercial NiO samples were measured to check the performance of the ΔE-Q3D detection system on 59Ni isobar separation and suppression. An overall suppression factor of about 107 for the interfering isobar 59Co resulting in detection sensitivity as low as 3.8×10-13 atomic ratio (59Ni/Ni) has been obtained. Based on these techniques, the AMS measurement method of 59Ni with high sensitivity is developed.
