Super-SIMS at HZDR: Status and Future — •Georg Rugel1, René Ziegenrücker1, Axel D.

The status and the future setup of the Super-SIMS at HZDR, Dresden will be outlined. The instrument is the combination of a commercial Secondary Ion Mass Spectrometry instrument (CAMECA IMS 7f-auto) with DREAMS (DREsden AMS). While the SIMS provides micron-scale lateral resolution, AMS ensures high selectivity through highly effective molecule suppression by the stripping process. High transmission for major element ions including silicon, fluorine and iodine has been demonstrated in initial tests (see ref. [1]). The high energies from our 6-MV tandem were not actually required for our background suppression needs. Our new compact 1-MV AMS system will be used in the future for Super-SIMS.
