The precise reconstruction of charged particle tracks in homogeneous liquid scintillator (LSc) neutrino detectors, e.g., from muons, is an important prerequisite for the efficient rejection of cosmogenic background events or the analysis of multi-GeV neutrino interactions. Topological information on such events, i.e., the reconstructed 3D density distribution of isotropically emitted scintilla ... More

The KATRIN experiment can perform a comparably low-statistics search for keV-scale sterile neutrinos with the first tritium measurements, improving the current laboratory limits on the squared sterile-to-active mixing angle by about one order of magnitude.

Since Kamiokande, the basic design of water-Cherenkov detectors has not changed: the walls of a water tank are lined with photodetectors that capture Cherenkov photons produced by relativistic particles. However, with this design the majority of photons are lost in insensitivie regions between photodetectors, while at the same time most photodetectors are outside the ring and remain dark.

The KArlsruhe TRItium Neutrino (KATRIN) experiment aims at the model-independent measurement of the electron neutrino mass. KATRIN is designed for a neutrino mass sensitivity of 0.2 eV (90\% CL) after three years of measurement time. In May 2018, KATRIN performed its First Tritium measurements. Along with the beta electrons, tritium beta decay creates ions inside the tritium source. The tritium io ... More

The GERDA (GERmanium Detector Array) experiment at the Laboratori Nazionali del Gran Sasso of INFN, Italy, is designed to search for neutrinoless double beta decay of $^{76}$Ge. In GERDA for the first time ever detectors are directly immersed in liquid argon which works as a cooling medium and as an additional active shield against external radioactivity. Phase II data taking started in December 2 ... More

In-situ production of long-lived isotopes by cosmic muon interactions may generate a non-negligible background for deep underground rare event searches. Previous Monte Carlo studies for the GERDA experiment at LNGS identified the delayed decays of $^{77}$Ge and its metastable state $^{77m}$Ge as dominant cosmogenic background contribution in the search for neutrinoless double beta decay of $^{76 ...

The liquid scintillator has 1.4 wt.% concentration of Zr, light yield of$48 \pm 7.1 $% for BC505, and an energy resolution of$2.5 \pm 0.4$% at 3.35 MeV assuming 64 % photo coverage. In order to investigate a half-life over$10^ ... More

The future neutrino experiment JUNO (Jiangmen Underground Neutrino Observatory) will determine the neutrino mass hierarchy by observing reactor neutrinos in liquid scintillator. To reach the required energy resolution of 3% @ 1MeV, a very good liquid scintillator transparency (attenuation length ≥ 20 m @ 430 nm) is required. To reach this transparency, it is planned to have several purification ... More

the Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose neutrino experiment under construction. The primary goal is to determine the neutrino mass hierarchy and precisely measure the oscillation parameters by detecting reactor anti-neutrinos. There will be around 20000 PMTs with a large photo-cathode of 20-inch equipped for the JUNO experiment, which includes 15000 MCP PMTs from NN ... More
