Abstract

In order to investigate the reaction of charged particles in the solar wind with neutral atoms in dust and gas shells of comets and other solar system objects, a new set of complex ion-optics for steering and decelerating a high charged partilce beam has recently been constructed at the Electron Beam Ion Trap at the Max-Planck-Institut für Kernphysik in Heidelberg. The projectiles are brought to collision with a neutral target in a reaction chamber. x-ray detector is used to identify the radiation emitted in the charge exchange reaction and also to start the time measurements, which are used for the coincidence experiments. Within this diploma thesis, a time-of-flight spectrometer was constructed and installed to investigate the ions produced during the charge exchange process (or recoil ions). The construction of the specifi c parts for this new time-of-flight spectrometer were drawn with the program SolidWorks 2008 and the electrostatic fields produced by the electrodes afterwards simulated in the program SIMION 8.0. These simulations specially focused on the convergence of the ion's time-of-flight and the distinction of diff erent charge states. After the assembly it was possible to identify the di fferent charge states during the measurements.
