Towards a low-background X-ray setup at Felsenkeller Dresden — •Christoph Seibt, Hans Fritz Rudolf Hoffmann, Marie Pichotta, Steffen Turkat, and Kai Zuber — Institute of nuclear and particle physics, TU Dresden, Germany

Gamma Spectrometry is one of the most commonly used tools in nuclear physics, and it has advanced over the last decades considering efficiency, resolution and background reduction. X-ray spectrometry on the other hand is barely used in the field of nuclear physics despite a wide range of applications in the field of rare nuclear decays. Low-background X-ray spectrometry may enable the investigation of decays with no gamma ray emission and decays with a low Q-value. Therefore, a low-background X-ray spectrometry setup is designed and installed in the Felsenkeller shallow-underground laboratory in Dresden, Germany. The setup consists of a Silicon Drift Detector, encapsulated by a multi-layer passive shielding. This presentation reports on the current status of the setup design, installation and background measurements.
