Description
CRESST is a multi-stage experiment directly searching for dark matter (DM) using
cryogenic $\mathrm{CaWO_4}$ crystals. Previous stages established leading limits
for the spin-independent DM-nucleon cross section down to DM-particle masses
below $1\,\mathrm{GeV/c^2}$. Furthermore, CRESST performed a dedicated search
for dark photons (DP) which excludes new parameter space
between DP masses of $300\,\mathrm{eV/c^2}$ to $700\,\mathrm{eV/c^2}$.
In this contribution we will discuss the latest results based on the previous
CRESST-II phase 2 and we will report on the status of the current CRESST-III
phase 1: in this stage we have been operating 10 upgraded detectors with
$25\,\mathrm{g}$ target mass each and enhanced detector performance since summer 2016. The improved detector
design in terms of background suppression and reduction of the detection
threshold will be discussed with respect to the previous stage.
We will conclude with an outlook on the potential of the next stage, CRESST-III
phase 2.
