摘要：
A novel direction-sensitive gamma ray detector is developed based on attenuation. The detector consists of 30 GAGG:Ce scintillators (2x2x20 mm(3)) closely arranged around a tungsten cylinder (diameter=22mm). The scintillation crystals are covered by the Teflon reflectors except for the readout faces. The GAGG:Ce array is read out by a SiPM array. When a source irradiates the detector, each crystal could generate a vector V-i. Where, the modulus of V-i is the event count of the crystal while the direction is the detector center to the crystal. The source direction can be simply determined using the sum vector. The detector is 360 degree sensitivity. Primary experiments have verified the concept of the detector. More experiments for detector performance evaluation will be carried out.
