用大面积雪崩光电二极管在近液氮温度下研究了纯NaI晶体。研究表明，137Cs源产生的光输出为44000±4000光子/MeV(ph/MeV)，对661.6keVγ射线的能量分辨率为5.9±0.2%，并且光产额与γ射线能量成良好的比例关系。研究还表明，在接近低温的情况下，冷却的激光二极管是研究闪烁体的一种很好的光电探测器。
The pure NaI crystal has been studied using a Large Area Avalanche Photodiode (LAAPD) at near liquid nitrogen (LN2) temperatures. The study showed a high light output of 44000±4000photons/MeV (ph/MeV), the energy resolution of 5.9±0.2% for 661.6keV γ-rays from a137Cs source and a good proportionality of the light yield versus γ-ray energy. It has been shown also that a cooled LAAPD is an excellent photodetector to study scintillators at near LN2temperatures.
