要旨:
In mass spectrometry the masses of atoms or molecules in a large mass range up to a
few thousand atomic mass units nowadays are determined by the so-called Fourier Transform
Ion Cyclotron Resonance (FT-ICR) method. The mass can be measured within a
few seconds with a high-precision of about 1ppm. Furthermore, ion species with a low
abundance of a few thousand ions can be detected. In this thesis the commissioning and
the characterization of such an FT-ICR mass spectrometer will be presented. The experiment
is installed at the Max Planck Institute for Nuclear Physics in Heidelberg. The mass
spectrometer is constructed in such a way that various detection and excitation schemes
can be investigated. Results concerning the one- and two-pulse quadrupolar excitation
schemes are presented. Since many ions are trapped simultaneously, space charge effects
play a crucial role. The observed phenomena like shielding of excitation fields and ionion
interaction are discussed. Here, many particle simulations are performed to understand
the observed phenomena. Furthermore, accuracy and precision limit studies of this mass
spectrometer are discussed.
