Summary:The special gamma spectrograph for moon exploration is provided with crystal scintillator connected to photomultiplier tube and data acquisition circuit successively and features that there are main detector and anticoincidence detector with scintillator connected to one other photomultiplier tube and that the photomultiplier tube of both the main detector and the anticoincidence detector are connected to the data acquisition circuit simultaneously. The data acquisition circuit has microprocessor. The novel gamma ray detection instrument has high sensitivity, low cost, optimal background radiation inhibiting effect and increased detector effective area. The optimal scheme has CsI (Ti) crystal in anticoincidence detector and crystal scintillator of several crystals adhered together.
