The CRESST-III experiment searches for direct interactions of dark matter with ordinary matter at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy. The main event signature would be a nuclear recoil in the scintillating target crystals.

Most promising detectors to search for particle dark matter are the xenon dual-phase time projection chambers (TPCs). This technology is by now well-established and can be scaled up to ton-scale. In this context, the XENON1T experiment currently holds the world-leading limit for direction detection of Weakly Interacting Massive Particles (WIMPs). Their next stage, XENONnT, will get a better...

The DEAP-3600 experiment is searching for WIMP dark matter with a 3.3 tonne single-phase liquid argon (LAr) target. Detector construction was completed at SNOLAB in 2016, and the experiment is currently taking physics data. Results from 1 year of open data (758 tonne-day exposure) were recently published, demonstrating stable detector operation and the power of pulse shape discrimination to...

The Karlsruhe Tritium Neutrino experiment (KATRIN) aims to determine the neutrino mass by measuring the tritium beta decay spectrum with a sensitivity of 0.2 eV (90 % C.L.). To reach this goal the spectrometer’s energy scale needs to be stable on the 60 meV level. This translates to a 3 ppm stability requirement for the high voltage creating the retarding potential (18.6 kV). The high voltage...

The goal of the Electron Capture in Holmium-163 (ECHo) experiment is the determination of the electron neutrino mass by the analysis of the electron capture spectrum of Holmium-163. The detector technology is based on metallic magnetic calorimeters operated at low temperature in a reduced background environment. During the first phase of the experiment, ECHo-1k, the detector production has...

When neutrinos interact via coherent elastic scattering with a nucleus, a tiny recoil is created. To be able to detect this recoil, special requirements have to be met. Detectors with a low enough noise threshold are needed and only recent developments make it possible to access the energy range where a detection is possible. Moreover, a large neutrino flux at energies within the regime of the...

The GERDA and MAJORANA experiments are searching for neutrinoless double-beta decay with germanium detectors enriched in the double-beta decaying isotope Ge-76. Building on their success in reaching background-free conditions and excellent energy resolution, the LEGEND experiment is planned to continue this search in a staged approach. One of the most efficient offline background reduction...

The SHiP experiment has been proposed as a general-purpose fixed-target facility at the CERN SPS North Area, with the start of data taking scheduled for 2026. Consisting of a two-fold detector, it combines the Search for Hidden Particles (SHiP) - such as Heavy Neutral Leptons (HNL) and light dark matter - with studies of tau neutrino physics.
