宇宙缪子被用来校准大面积中子阵列(LANA)的位置、光输出和相对定时偏差。每个2×2m2的LANA墙由25个水平中子探测棒组成。每根棒长2m，截面6.35×7.62cm2，容器内装满了NE-213有机闪烁液。结果表明，棒的平均位置和时间分辨率分别约为8 cm和500ps半高宽。我们的方法提供了一种准确、快速和方便的LANA校准方法，可以在不使用放射源或束流的情况下应用于普通闪烁阵列。
Cosmic muons are used to calibrate the position, light output and the relative timing offset of the Large Area Neutron Array (LANA). Each 2× 2 m 2 LANA wall consists of twenty-five horizontal neutron detection bars. Each bar is 2 m long with a cross-section of 6. 35× 7. 62 cm 2 Pyrex container filled with NE-213 organic scintillation liquid. The average position and time resolution of a bar is found to be about 8 cm and 500 ps FWHM, respectively. Our method provides an accurate, fast and convenient calibration of LANA that can be applied to general scintillation arrays without the use of radioactive sources or beams.
