DREAMS - a universal AMS facility based on the 6 MV - TandetronTM at FZD in Dresden

Akhmadaliev, S.; Kolitsch, A.; Merchel, S.; Möller, W.

A new accelerator mass spectrometry (AMS) system has been installed at the Forschungszentrum Dresden-Rossendorf (FZD). The system is based on a 6 MV-TandetronTM accelerator produced by High Voltage Engineering Europe (HVEE). The AMS facility is specified for measurements of 10Be, 14C, 26Al, 36Cl, 41Ca and 129I with isotopic ratios of 10-10 - 10-16 and precision better than 0.3% for 14C/12C.
The system uses a bouncer sequential injector with two Cs-sputter ion sources and a 54°-electrostatic analyser (ESA). On the high-energy site it has a 90°-analysing magnet, Faraday-Cups for stable nuclides, a 35°-ESA, a post-stripper foil, and a 30°-vertical magnet for suppression of interfering species, and gas ionisation chamber for detection of radionuclides [1].
The Cockroft-Walton type high voltage generator provides a terminal voltage of up to 6 MV. The system is additionally equipped with a multipurpose ion injector containing a third Cs-sputter ion source and a duoplasmatron for high-energy ion implantation and ion-beam materials analysis.
