Characterisation of an ultra low-background point contact HPGe well-detector for an underground laboratory
Since a few years there are well-type HPGe-detectors with a small, point-like, anode contacts available commercially. This paper describes the characterisation of the first ultra low-background, so-called, SAGe™ well detector with regards to resolution and background performance. Inside a passive lead/copper shield in the underground laboratory HADES a background count rate of 690 ± 6 d−1 (268 ± 3 d−1 per kg Ge) was recorded 19 months after taking it underground.
