The goal of CRESST-III is to further increase its sensitivity - especially for low dark matter particle masses. Therefore, the mass of the detector crystals
was reduced by a factor of about 10 to 24g. In this way, detector thresholds below 100eV can be achieved.
On the left an opened CRESST-III detector module can be seen. Both, the block-shaped CaWO4 detector crystal as well as the SOS light detector are held by
CaWO4 sticks to ensure a fully scintillating housing surrounding the detectors. On the right, a first heat pulse with an energy of 500eV recorded by such a detector is shown.
