The combination of a mass spectrometer with an accelerator allows very sensitive detection limits for many applications. At the Helmholtz-Zentrum Dresden-Rossendorf an AMS (accelerator mass spectrometry) facility, DREsden AMS (DREAMS), with a 6-MV tandem accelerator has been successfully installed [1]. DREAMS has its applications in many scientic fields by determining 10Be, 26Al, 36Cl and 41Ca. We made progress to develop a negative ion source for volatile elements like chlorine or iodine by reducing the memory effect [2]. The range of isotopes is broaden to higher masses by the first experiments with actinides. A time-of-flight beam line will enable the measurement at higher count rates and of additional isotopes. Another focus is the combination of a commercial SIMS (CAMECA 7f Auto) with the accelerator. For this so called Super-SIMS the CAMECA 7f is utilized as ion source and low energy mass spectrometer. By complete destruction of molecules in the stripping process at the terminal of the accelerator detection limits some orders of magnitude better than for traditional dynamic SIMS are expected, i.e. ~10-9-10-12, see e.g. [3]. The Focus of applications will be geological samples in the framework of resource technology research. Ref.: [1] S. Akhmadaliev et al., NIMB 294 (2013) 5. [2] S. Pavetich et al., this conference.
