Abstract
A new beamline for AMS measurements has been built at the Erlangen EN tandem accelerator. The main components at the low-energy side of the accelerator are a cesium sputter ion source and a 90° injection magnet. At the high-energy side, a 15° electrostatic sector field, a 55° analyzing magnet for the separation of Be and C isotopes, and a gas-filled ionization chamber are used. In 14C test measurements of charcoal, pit-coal and graphite samples, using a preliminary and simple ion source, the 14C events could be clearly separated from the background. The system will be completed with a newly developed high-current ion source, which is presently being installed, and with a 120° mass spectrometer, which will be used for measuring heavier ions such as 26Al, 36Cl, 90Sr and 129I.
