| Abstract: | In order to improve the power of isobaric identification in the accelerator mass spectrometric measurements, a new gas detector called gas-filled time-of-flight spectrometric detector has been set up. The principle, construction and method of the 241Am test were researched. Through increasing the energy of ions, selecting suitable gas and distance of flight, it can improve the absolution of GF-TOF to detect the isobars. |
