LaCI3 crystal (also known as lanthanum chloride crystal ) is a kind of scintillation crystal with excellent comprehensive performance, which is widely used in the field of high energy physics and nuclear logging. LaCI3 crystal has high-temperature resistance, and its optical output is almost constant in the temperature range of room temperature to 220 ℃. It can fully meet the temperature demand of underground logging. LaCI3 has stable physical and chemical properties, high thermal conductivity, and resistance to harsh environments. It has excellent scintillation performance, such as high scintillation efficiency, stable light output, fast to decay time (about 28ns ), low energy resolution (< 3.3% @ 662kev ). Laci3 crystal is widely used γ Detector (γ-ray logging), Neutron Detector (neutron logging) , Nuclide identification instrument and other equipment.
