Entwicklung und Inbetriebnahme eines Vorschaltgerätes zur Impedanzmessung von Silizium-Photomultipliern

In this thesis an electric ballast has been developed and put into practice which can be used to run impedance measurements for SiPMs. Dierent platine designs of the electric ballast are analysed. The disign exhibiting the best performance has been used for further measurements. Furthermore this thesis shows that running impedance measurements with this electric ballast for easy electric devices like an inductor or a capacitor is a substantial progress compared to previous methods. With this knowledge the impedance of SiPMs can be measured. Problems with the calibration at the electric ballast are solved by an own calculated calibration. Finally a known SiPM with a voltage between 0-70 V was measured.
