Initial tests of Al-26 fluoride target matrix on MILEA AMS system
Original language description
In this study, the possibility of using a superhalogenide ion AlF4- extracted from Na3AlF6 based target materials for Al-26/Al-27 measurements by Accelerator Mass Spectrometry (AMS) was investigated. Determination of Al-26 by usual mass spectrometric methods is generally hampered by the presence of the isobar Mg-26. However, the AMS method enables significant suppression of this interference, particularly by negative ion formation. After initial current tests in a caesium sputtering ion source of the Tandetron system, performance of the fluoride materials was analysed on the MILEA AMS system at ETH Zurich. The AlF4- current was used to evaluate the performance of the respective samples. Additives as PbF2 were tested to increase the extracted ion currents and samples containing MgF2 were used to investigate the presence of isobaric ions. Subsequently, the ionization efficiency of AlF4- was determined by recording the Al-27(2+) current on the high energy side and the signals of Al-26(2+) were investigated with the gas ionization detector.
