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. In th ... More

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 to ... More

A convincing observation of neutrino-less double beta decay (0&nu;DBD) 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 particle i ...

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 orde ... More

CALDER is a R&D project for the development of cryogenic light detectors with an active surface of 5x5cm$^{2}$ and an energy resolution of 20eV RMS for visible and UV photons. These devices can enhance the sensitivity of next generation large mass bolometric detectors for rare event searches, providing an active background rejection method based on particle discrimination. A CALDER detector is c ... More

The MAJORANA DEMONSTRATOR is a neutrinoless double beta decay experiment utilizing enriched Ge-76 detectors in 2 separate modules inside of a common compact shield at the Sanford Underground Research Facility. The DEMONSTRATOR has developed specialized processes for producing ultra-pure copper and plastic components and world leading assay sensitivities to validate their cleanliness. The experimen ... More

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 scin ... More

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 *10^25 ...

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 decay c ... More

News Experiment With Sphere- Gaseous (NEWS-G) detector is a world wide collaboration based on spherical gas detector for Light Dark Matter search. The first low radioactivity spherical detector, SEDINE (60 cm diameter), installed at LSM on 2012 is continuing to take data. The next detector, 140 cm in diameter, will be fabricated using remarkable ultra-low radioactivity (few microBq/kg). This l ... More

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 sear ... More

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 campaign ... More

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 liqu ... More
