Actually, a Super-SIMS-Set-up is developed at the HZDR Ion Beam Centre (IBC) by connecting a conventional SIMS-source (SIMS = Secondary ion mass spectrometry) to a 6 MV tandem accelerator. Due to the acceleration of the extracted secondary ions to MeV-energies and their charge reversal from negative to positive ions, Super-SIMS can reach about 2 to 3 orders of magnitude lower detection limits (up to 10-12 or ppt, highly depending on analyte and matrix) as conventional SIMS.
The basis for a coordinated control software between ion source (SIMS instrument), accelerator and the detectors of the high-energy mass spectrometer is a sound knowledge of the flight time of ions in the mass range between 1 and 300 amu and the complete energy range on the low and high-energy side.
The aim of the thesis is the establishment of a small software tool which allows the simulation of the critical time line of given ions in a broad range of ion optical conditions. The simulation should base on ion optical simulations done with the LIMIOPTIC (www.limioptic.de) and SIMION® (http://simion.com/) codes.
It is the intention that the software tool runs either independently or could be integrated in the future control software of the Super-SIMS.
