Abstract
LYCCA is a detector system consisting of different types of detectors which can be used flexibly to
meet the individual requirements of different experiments focused on studying exotic nuclei far off the
line of stability. It was developed for the HISPEC/DESPEC programme which is part of the NUSTAR
collaboration at the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany.
This bachelor thesis deals with a part of this detector system, namely the LYCCA DeltaE-E-telescopes
consisting of a DSSSD and a CsI(Tl) block used to track and identify heavy atomic nuclei moving
at relativistic velocities. The telescopes have to be assessed with regard to overall performance and
energy resolution after their first in-beam... (More)

This bachelor thesis deals with a part of this detector system, namely the LYCCA DeltaE-E-telescopes
consisting of a DSSSD and a CsI(Tl) block used to track and identify heavy atomic nuclei moving
at relativistic velocities. The telescopes have to be assessed with regard to overall performance and
energy resolution after their first in-beam use in the PRESPEC-AGATA campaign in 2012.
The functionality of the two types of detectors is explained, and the setup and procedure for the
testing measurements are described. Furthermore, the analysis and the obtained results are presented.
The energy resolution for the DSSSDs is determined to be 0.45-0.74% for 8.78 MeV alpha-particles and
assessment is further done based on their leakage current, which shows clear differences between different
detectors. The CsI(Tl)/PD units are mainly examined for leakage current and it is found that
91 out of the 144 units fulfill the detector acceptance criteria. (Less)
