Abstract

The contribution of magnet saturation and relativistic correction in an accelerator mass spectrometry (AMS) system has been studied. We show that for analyzing magnet excitation above 1.3 T, the magnet saturation has to be taken into account in AMS systems. For ions faster than 0.1 c the relativistic correction has been found significant. If these two well-known phenomena are not taken into account in the scaling of the system for a rare isotope, based on the tuning of an isotope pilot beam, losses as high as factor of 1.5 can occur. Two actual cases, ¹⁴C and ¹²⁹I, are considered.
