Status of routine operation and developments at DREAMS

Rugel, G.; Merchel, S.; Scharf, A.; Ziegenrücker, R.; DREAMS-Users

Since fall 2011, the DREsden AMS-facility (DREAMS), has performed routine AMS at the Ion Beam Centre’s (IBC) 6 MV tandem accelerator located at the Helmholtz-Zentrum Dresden-Rossendorf [1, 2]. The accelerator is shared with others for purposes such as ion beam analysis and high-energy ion implantation. Measurements of 10Be, 26Al, 36Cl, 41Ca, and 129I are routinely performed for a wide range of applications. Samples are prepared in close cooperation with DREAMS’s users, mostly in our two dedicated, high quality laboratories on-site [3]. One particular ion source with a very low long-term memory is used exclusively for measuring the halogens (36Cl and 129I) [4]. For measurements of 26Al/27Al ratios we have reduced the background to 6×10-16. Additionally, we started to investigate the potential for non-routine AMS-nuclide determination (stable and short-lived) for e.g. astrophysical applications.
