The temperature dependence of the pulse length was measured for an 18-fold segmented n-type germanium detector in the temperature range of 77–120 K. The interactions of 122 keV photons originating from a 152Eu source were selected and pulses as observed on the core and segment electrodes were studied. In both cases, the temperature dependence can be well described by a Boltzmann-like ansatz.
