论文摘要
ARTI是一个完整的框架,旨在模拟由单个,多个,多个甚至偶数的相互作用而产生的二次粒子产生的信号,这是主要宇宙射线与大气的完整通量。这些信号是为任何位置(纬度,经度和高度)的任何粒子检测器模拟的,包括实时大气,地磁和探测器条件。它通过用C ++,Fortran,Bash和Perl编写的一系列代码进行配合,提供了三种不同的仿真环境的易于使用的集成:Magnetocosmic,Corsika和Geant4。这些工具评估了对主要通量,宇宙射线的大气阵雨以及探测器对颗粒二次通量的响应的地磁场影响。在这项工作中,我们通过计算拉丁美洲巨型天文台选定地点的信号的总预期通量来展示ARTI框架的使用情况,这是位于拉丁美洲的宇宙射线天文台,该天文台位于拉丁美洲,覆盖了广泛的海拔高度,纬度和地理磁性。 ARTI还计算出在突然发生的伽马射线爆发或源自稳定γ源的能量光子的通量中预期的信号通量。它还将这些通量与预期的背景进行了比较,以在部署在高海拔位置的单个水cherenkov检测器中检测这些现象。更重要的是,通过使用ARTI,可以以非常精确的方式计算高能MUON和其他次要的预期通量,并在地质结构上注入用于混血应用的地质结构。
ARTI is a complete framework designed to simulate the signals produced by the secondary particles emerging from the interaction of single, multiple and even, the complete flux of primary cosmic rays with the atmosphere. These signals are simulated for any particle detector located at any place (latitude, longitude and altitude), including the real-time atmospheric, geomagnetic and detector conditions. Formulated through a sequence of codes written in C++, Fortran, Bash and Perl, it provides an easy-to-use integration of three different simulation environments: magnetocosmic, CORSIKA and Geant4. These tools evaluate the geomagnetic field effects on the primary flux, the atmospheric showers of cosmic rays and the detectors' response to the secondary flux of particles. In this work, we exhibit the usage of the ARTI framework by calculating the total expected flux of signals at eight selected sites of the Latin American Giant Observatory, a cosmic ray Observatory located in Latin America covering a wide range altitudes, latitudes and geomagnetic rigidities. ARTI also calculates the flux of signals expected during the sudden occurrence of a gamma-ray burst or the flux of energetic photons originating in steady gamma sources. It also compares these fluxes with the expected background to detect these phenomena in a single water Cherenkov detector deployed in high altitude sites. Even more, by using ARTI, it is possible to calculate in a very precise way the expected flux of high energetic muons and other secondaries on the ground and to inject it over a geological structure for muography applications.
