Abstract：
The research and development of a new type detector for solar neutrino detection is introduced. The detector uses two types of scintillators: one is the gadolinium(Gd) loaded liquid scintillator with the concentration of 5%, for which the light attenuation length is ≥150cm and the energy resolution is 21%(standard deviation) for 60keV Gamma-ray; the other is a 1cm×3cm GSO:Ce crystal, which has the light yield 20% with respect to the NaI:Tl, the light decay time 60ns and the energy resolution 9.2%(standard deviation) for 662keV Gamma-ray. The characters of the detector composed by both scintillators for solar neutrino detector and the methods to suppress the backgroud are discussed. A simulation for such detector with the size 10cm×50cm shows the light collection efficiency can reach 20%.
