This work has been developed between Politecnico di Torino and Universität Stuttgart, in the Institut für Raumfahrtsysteme (IRS). A laboratory model for the Destiny+ Dust Analyzer (DDA) Time-of-flight (TOF) Mass Spectrometer is designed, developed and experimentally characterized. A basic and simple design is created to exploit as much as possible the cylindrical symmetry of the instrument. Using the Software SIMION 8.1, simulations and tests are conducted to investigate the response function of the detector and to optimize the geometry and the electrical potentials applied on every component. Features of the ions after an impact ionization are studied and implemented in the simulation workbench, in order to analyse their effect on the TOF Spectrum.
