Abstract：
The characters of a kind of new detector, "CaF ₂(Eu)+liquid scintillator" mixed WIMP detector, which is proposed by Beijing Group, are introduced. The preliminary design of the structure of this detector has been made, by studying its optical collection efficiency with simulation. In addition, it shows that the mixed detector would be good at excluding the backgrounds, which are produced by the decays of the radioactive contamination inside the detector.
