Abstract
The long lived radioactive nuclide 60Fe is interesting in many research fields such as astrophysics and nuclear physics. Taking the advantage of the high energy of HI-13 tandem AMS system and the high performance of a Q3D magnetic spectrometry at CIAE, the measurement method of 60Fe is being developed. As first step, 58Fe and 58Ni are used for simulating 60Fe and 60Ni for optimizing the measurement conditions and checking the ability of isobar suppression. The results shown that an overall suppression factor of more than 1011 can be obtained by using the ΔE-Q3D technique in combination with a four-anodes gas ionization chamber. Based on the findings a detection sensitivity of 60Fe/Fe ∼ 10−15 can be anticipated.
