扩展四面体NaI（Tl）谱仪的宇宙μ子刻度
Calibration of The Extended Quadrahedral NaI(Tl) Spectrometer by Cosmic Muons
摘要：
本文介绍了用宇宙μ子标定扩展四面体NaI（Tl）谱仪的结果。光谱仪的信号幅度和能量分辨率对光电倍增管处的电压和粒子在横向方向上进入光谱仪的入口点具有复杂的依赖性。当光电倍增管分压为U = 1150V时，在谱仪长度的90%处观察到均匀信号区，能量分辨率约为7%。
英文摘要：
The results of the extended quadrahedral NaI(Tl) spectrometer`s calibration by cosmic muons are presented. The signal amplitude and energy resolution of the spectrometer have complex dependencies on the voltage at the photomultiplier and the entry point of the particle into the spectrometer in the transverse direction. When the voltage across the photomultiplier divider photomultiplier is U = 1150 V the homogeneous signals area is observed at about 90% of the spectrometer length, the energy resolution is about 7%.
