| 摘 要： | 讨论了测量超高能宇宙线的τ中微子望远镜(CRTNT)的性能. 利用Monte Carlo方法对探测器作了详细的模拟, 并研究了探测器以一个塔形主探测器和两个高视角辅探测器协同触发的布局, 以及对大气簇射作立体观测时的物理性能. 计算了当能量高于1017eV时, 探测器的有效面积. 用于第2个膝区物理研究时事例率估计可达20k个/年. 还估算了与其他探测器交叉定标的事例率. 比较和优化了探测器的不同几何布局.

| Abstract: | Cosmic Ray Tau Neutrino Telescopes (CRTNT) for sub-EeV cosmic ray measurement is discussed. Performances of a stereoscope configuration with a tower of telescopes plus two side-triggers are studied.This is done by using a detailed detector simulation driven by Corsika.Detector aperture as a function of shower energy above 10~(17)eV is calculated.Event rate of about 20k per year for the second knee measurement is estimated.Event rate for cross calibration with detectors working on higher energy range is also estimated. Different configurations of the detectors are tried for optimization. |
