The present invention provides an accelerator mass spectrometry device for simultaneously measuring isotopes. In one embodiment, the device comprises a sputtering negative ion source for generating negative ions; the sputtering negative ion source being connected to an accelerating tube for simultaneously accelerating a plurality of isotopic ions; an output end of the accelerating tube being connected to an isotope mass resolution system; the isotope mass resolution system being connected to a charge conversion analysis and multi-receiving measurement system; the charge conversion analysis and multi-receiving measurement system being connected to an ion detection system. The present invention is capable of accelerating a plurality of isotopic negative ions simultaneously. The accelerated isotopic negative ions are separated. Stable isotopic negative ions are measured by a stable isotope receiver. Unstable isotope negative ions are converted to positive ions and then measured by a detector.
