Abstract

The next generation direct dark matter experiment CRESST-III has a high potential to significantly increase the sensitivity to low-mass WIMPs (m_x ≲10GeV/c²). We present the new CRESST detector module: it consists of a 24 g CaWO₄ crystal operated as a phonon detector and a 20×20 mm² silicon-on-sapphire light detector. The phonon energy threshold is lowered to ∼100eV and a light detector resolution of typically 5eV is achieved. A fully-scintillating inner detector housing is realised which efficiently rejects events from surface-alpha decays. The CaWO₄ sticks holding the target crystal are also operated as calorimeters to discriminate all possible artefacts related to the support structure. A projection for the sensitivity to spin-independent WIMP-nucleon scattering is given for the first phase of CRESST-III which will start beginning of 2016.
