Description
The GERDA and MAJORANA experiments are searching for neutrinoless double-beta decay with germanium detectors enriched in the double-beta decaying isotope Ge-76. Building on their success in reaching background-free conditions and excellent energy resolution, the LEGEND experiment is planned to continue this search in a staged approach. One of the most efficient offline background reduction techniques in these searches is pulse shape discrimination using the signal shape coming from the Ge detectors. In order to understand and distinguish the signal shape from different background sources, simulations and test measurements are performed. I will introduce the concepts of signal generation in germanium detectors by presenting a new open source pulse shape simulation software developed at the MPI for Physics. Also I will discuss some of our test stand measurements studying surface effects and temperature dependence.
