Abstract

The results of cosmic muon calibration of the extended quadrihedral NaI(Tl) spectrometer are presented. The signal amplitude and energy resolution of the spectrometer in the direction transverse to the spectrometer axis have complex dependences on the photomultiplier voltage and particle entrance point to the spectrometer. At a photomultiplier divider voltage U = 1150 ± 10 V, the region of uniform signals is observed over ~90% of the spectrometer length, the relative energy resolution is δ ≈ 7%.

宇宙峰校正四面体NaI（Tl）光谱仪

摘要

提出了扩展四面体NaI（Tl）光谱仪的宇宙μ子校准结果。在垂直于光谱仪轴的方向上光谱仪的信号幅度和能量分辨率对光电倍增管电压和粒子进入光谱仪的入射点具有复杂的依赖性。在光电倍增器分压器电压U = 1150±10 V时，在光谱仪长度的〜90％范围内观察到均匀信号区域，相对能量分辨率为δ≈7％。
