Quenching of deduced from the -spectrum shape of Cd measured with the COBRA experiment
Lucas Bodenstein-Dresler, Yingjie Chu, Daniel Gehre +17
A dedicated study of the quenching of the weak axial-vector coupling strength in nuclear processes has been performed by the COBRA collaboration. This investigation is…
Suppression of alpha-induced lateral surface events in the COBRA experiment using CdZnTe detectors with an instrumented guard-ring electrode
J. -H. Arling, M. Gerhardt, C. Gößling +11
The COBRA collaboration searches for neutrinoless double beta-decay (-decay) using CdZnTe semiconductor detectors with a coplanar-grid readout and a surrounding guard-ring st…
The Dortmund Low Background Facility - Low-Background Gamma Ray Spectrometry with an Artificial Overburden
Holger Gastrich, Claus Gößling, Reiner Klingenberg +5
High-purity germanium (HPGe) detectors used for low-background gamma ray spectrometry are usually operated under either a fairly low overburden of the order of one meter of water e…
Results of a search for neutrinoless double-beta decay using the COBRA demonstrator
Joachim Ebert, Matthew Fritts, Daniel Gehre +18
Neutrinoless double- decay ( decay) is a hypothetical process that can occur if the neutrino is its own antiparticle. The COBRA collaboration operates a demonstrator to se…
Long-Term Stability of Underground Operated CZT Detectors Based on the Analysis of Intrinsic Cd β-Decay
J. Ebert, C. Goessling, D. Gehre +17
The COBRA collaboration operates a demonstrator setup at the underground facility LNGS (Laboratori Nazionali del Gran Sasso, located in Italy) to prove the technological capabiliti…
