Schottky diagnostics uses the noise of the beam current in an ion storage ring, called the Schottky noise, to determine beam properties such as the momentum spread and the beam energy. In this thesis, Schottky diagnostics as well as the characteristics of the Schottky pick-up were discussed in theory. In experiments, two different electrostatic pick-ups were used to verify the properties of the Schottky pick-up and the theory of Schottky diagnostics. For the experiments, a 12C6+ ion beam with an energy of 50 MeV was used. Signal distortions like amplification with a preamplifier and damping of the signal through long cables must be taken into account when analyzing the data. Hence, the frequency responses of the utilized amplifiers and cables were measured and used to adjust the recorded signals. The experimental data was compared to the theoretical expectations. Conclusions were drawn to model a new Schottky pick-up that will be in use in the cryogenic storage ring (CSR).
