Scientific paper

We present the computer simulation design and calibration experiments of an impact-ionization dust analyzer with a new optical system of TOF-MS (Time-Of-Flight Mass Spectrometer). A TOF-MS with curved potential ion mirror has been developed to be on board spacecraft for in-situ dust analysis. An ion mirror with curved potential proved to increase mass resolution as compared with conventional (parallel potential) so called reflectron. Elemental and isotopic abundance of the impacting dust is analyzed to distinguish their different origins. This TOF-MS will fit for many future interplanetary exploration missions as well as circum-earth orbiters.
