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.
We list here the available datasets from CRESST-II and CRESST-III. The data can be downloaded for use or dynamically visualised within the repository. Please note the appropriate sources listed for citation when using data from the CRESST Collaboration.
