Simulation of ultra-high energy photon propagation with PRESHOWER 2.0

Abstract
In this paper we describe a new release of the PRESHOWER program, a tool for Monte Carlo simulation of propagation of ultra-high energy photons in the magnetic field of the Earth. The PRESHOWER program is designed to calculate magnetic pair production and bremsstrahlung and should be used together with other programs to simulate extensive air showers induced by photons. The main new features of the PRESHOWER code include a much faster algorithm applied in the procedures of simulating the proc...

摘要
在本文中，我们介绍了PRESHOWER程序的新版本，该程序是一款用于模拟超高能光子（ultra-high energy photons）在地球磁场中传播的蒙特卡洛模拟（Monte Carlo simulation）工具。PRESHOWER程序旨在计算磁正负电子对产生与轫致辐射（bremsstrahlung），需与其他程序配合使用，以模拟光子引发的广延空气簇射（extensive air showers）。该代码的主要新特性包括在模拟相关流程中采用了速度大幅提升的算法……
