This high-purity germanium detector is located in the Felsenkeller shallow-underground laboratory and is operated by the Institute for Nuclear and Particle Physics. It is shielded against cosmic radiation by 45m of rock overburden and is suitable for measuring samples with an activity in the milli to micro-Becquerel range. A sophisticated lead castle made of high-purity materials and an anti-radon box for flushing radioactive radon gas out of the interior of this setup additionally acts as shielding. An active muon veto, consisting of five scintillation crystals, represents the latest upgrade of this setup and makes this detector one of the most sensitive gamma detectors in the world.

Für Messungen sprechen Sie bitte Prof. Dr. Kai Zuber oder die Mitarbeiter der Professur Kernphysik an.

This detector can also be used for activation measurements together with the Felsenkeller 5 MV underground ion accelerator (https://dresden-technologieportal.de/en/equipment/view/id/2934).
