Optical set-up for automatised SiPM characterisation

In this work the construction and the initial operation of an automatised test set-up for the electrical and optical characterisation of Silicon Photomultipliers (SiPMs) is described. A characterisation of SiPMs is required to exploit their full potential in detectors.The aim of this work was the construction of a test set-up with the capability to measure the SiPM properties in a 4D parameter space (temperature, operating voltage, wavelength of the light and light intensity). The successful implementation of the goal is shown.The test set-up consists of the light source, the optical set-up for light distribution, the temperature stabilisation, the measuring instruments, and a custom-made control and data acquisition software which are all presented in this thesis.The measuring methods for the different SiPM properties are explained and the results are shown
