The SABRE (Sodium-iodide with Active Background REjection) experiment is designed to search for WIMP dark matter via detection of an annually modulating signal.
The DAMA/LIBRA experiment claims the observation of a modulation compatible with dark matter detection. However, the candidate dark matter signal has not yet been confirmed by other experiments. SABRE will perform a high sensitivity...

The objective of the Karlsruhe Tritium Neutrino experiment (KATRIN) at the Karlsruhe Institute of
Technology (KIT) is the measurement of the effective electron neutrino mass with a sensitivity of
200 meV/c$^2$. A central component is the Main Spectrometer (MS), a MAC-E filter type
electrostatic high pass filter for electrons. It measures the energy of $\beta$-electrons from
tritium...

The KArlsruhe TRItium Neutrino (KATRIN) experiment aims to determine the effective mass of the electron antineutrino
with an unsurpassed sensitivity of 200 meV/c$^2$ in a direct model-independent approach.
Located at the Karlsruhe Institute of Technology (KIT) the experiment uses a MAC-E filter type
electrostatic Main Spectrometer (MS) to investigate the tritium $\beta$-decay spectrum close...

Neutron-induced nuclear recoils present one of the dominant backgrounds in many low-background experiments. These neutrons are largely radiogenic in origin, coming from fission and ($\alpha$,n) reactions in detector components. The ($\alpha$,n) neutron production rate in a material depends on the composition of the material as well as the energies of the $\alpha$ decays that occur within it....

The LZ dark matter experiment will require an unprecedented low background rate within its fiducial volume, defining strict constraints on radioactivity from construction materials. The radioactive background is further mitigated through the combination of powerful self-shielding from liquid xenon, 3D event vertex reconstruction, and external veto detector systems. An aggressive screening...

CANDLES aims to measure neutrino-less double beta decays using $^{48}$Ca which has the highest Q value (4.27 MeV) among all isotope candidates of double beta decays. A distinction in the measurement is an active veto system using liquid scintillator. Large amount of external backgrounds reacted in LS can be removed by taking advantage of the pulse shape difference between CaF$_{2}$ and liquid...

The GERDA experiment is designed to search for neutrinoless
double beta decay of Ge-76. In its second phase 37 HPGe detectors enriched
in the isotope Ge-76 are directly immersed into liquid argon.
The radio-pure cryogenic liquid acts as passive and active shield
and as a cooling medium for the detectors simultaneously.
Recently a half-life limit on 0vbb decay of Ge-76 of
T1/2 > 5...

The Cryogenic Underground Observatory for Rare Events (CUORE) will search for the neutrinoless double-beta ($0\nu\beta\beta$) decay of $^{130}$Te using a 19 tower array of 988 high-resolution TeO$_{2}$ bolometers.
The goal of CUORE is to reach a $2\times10^{26}$ year 1-sigma sensitivity on the $^{130}$Te $0\nu\beta\beta$ decay half-life, which CUORE can achieve if the background index is the...

A convincing observation of neutrino-less double beta decay (0νDBD) pivots on the possibility of operating high-energy resolution detectors in background-free conditions. The CUPID-0 experiment is the first step of a next generation project based on cryogenic calorimeters equipped with light detectors able to measure the scintillating light produced in the scintillating absorbers for...

Thanks to the 2400 m overburden and the long distance to commercial reactors, the China Jinping Underground Laboratory (CJPL) is an ideal site for low background neutrino experiments. The Jinping Neutrino Experiment will perform an in-depth research on solar neutrinos, geo-neutrinos and supernova relic neutrinos. Many efforts were devoted to the R&D of the experimental proposal. A new type of...
