摘要

NOvA实验旨在研究加速器中微子束的振荡。由于探测器的大尺寸和高分割度，以及灵活的程序触发和数据采集系统，可以在NOvA中检测和研究大气中微子。本文提出了一种用于远端探测器大气中微子配准的方法：概述了触发器的选择和重建过程，计算了它们对背景和信号事件的效率，最后给出了大气中微子的预期能谱。

Atmospheric Neutrino Detection Efficiency Estimation in the NOvA Experiment

The NOvA experiment is designed to study oscillations in an accelerator neutrino beam. Due to the large size and high segmentation of the detectors, as well as a flexible system of program triggers and data acquisition, atmospheric neutrinos can be detected and studied in the NOvA. This paper presents a developed methodology for atmospheric neutrino registration in the far detector: it outlines the procedure for selecting and reconstructing triggers, calculates their efficiency for background and signal events, and finally, provides the expected energy spectrum of atmospheric neutrinos.
