原始语种摘要: Abstract(#br)Drifts in the accelerator stability as well as those in beam transport components are the main limitations in achieving high precision in accelerator mass spectrometry (AMS). In order to achieve the high precision required for isotopic geology and geochronology applications, the sequence of isotopes of interest should be counted for as short an interval as possible. While fast isotope switching can be achieved readily at the low-energy end, it has hitherto not been possible to do so at the high-energy end. For a narrow range of transmission typical for most analysing magnets, fast switching (<1 ms) of the field is not possible if steady state is also desired. We have devised a novel electric means to modulate the beam trajectory in a static magnetic field for the AUSTRALIS...
