Investigation of ${\hbox {ZnWO}}_{4}$ Crystals as Scintillating Absorbers for Direct Dark Matter Search Experiments

A high light yield at low temperatures is one of the key criteria in the choice of scintillating target crystals for the CRESST-II dark matter search. We perform a feasibility study on ZnWO 4 crystals as scintillating targets for the CRESST-II experiment. The light yield and the quenching factors of at mK temperatures are given for the first time.
