CRESST Experiment

CRESST is a direct dark matter search experiment based on cryogenic particle detectors to search for nuclear recoil events induced by the elastic scattering of dark matter particles off nuclei. The setup is installed in a deep underground site under the Gran Sasso massif in Italy with the detector modules operating at about 15mK.

The first phase of the CRESST experiment (CRESST I) used sapphire crystals as target material. Energy deposited in these crystal via a particle interaction is detected as a heat signal read out with superconducting phase transition thermometers - transition edge sensors (TES).

The detector modules for CRESST II and CRESST III were developed based on scintillating CaWO4 crystals as absorbers. In this crystal a particle interaction produces mainly heat in the form of phonons, as for sapphire. In addition a small amount of the energy deposited is emitted as scintillation light. As the amount of light produced differs for different kinds of particles, this leads to an efficient means of eliminating the most common backgrounds.

The XENON Experiment

The XENON experiment is a 3500kg liquid xenon (LXe) detector to search for Dark Matter. It is a dual-phase time projection chamber (TPC) housed at the INFN Laboratori Nazionali del Gran Sasso. Particles recoiling in LXe produce photons (scintillation) and electrons (ionization).

The photons are detected as the “S1” signal with 248 3-in. photomultiplier tubes (PMTs) positioned above and below the LXe target. Electric fields drift the electrons upward and extract them into gaseous xenon, where electroluminescence produces a secondary scintillation “S2” signal.

In most analyses, the ratio between S1 and S2 differentiates electronic recoils (ERs), caused by β particles and γ rays, from nuclear recoils (NRs), caused by neutrons or some DM particles. The interaction position, reconstructed from the S2 light pattern and the time difference between S1 and S2, discriminates DM candidates from most external radioactive backgrounds.
