不同太阳条件下日球层质子和反质子调制及AMS-02测量预报
Proton and antiproton modulation in the heliosphere for different solar conditions and AMS-02 measurements prediction
摘要：
银河宇宙射线主要是质子，被限制在银河磁场中，在银河系内部形成各向同性的通量。在到达地球轨道之前，它们进入日球层并经历扩散、对流、磁漂移和绝热能量损失。其结果是减少了低能量（低于10 GeV）的粒子通量，称为太阳调制。我们实现了一个准时变的太阳调制的二维随机模拟，能够再现CR光谱一旦已知的本地星际光谱（LIS）。我们能够估计粒子和反粒子的日光层调制的极性依赖性相关的不同行为。与AMS-01、Pamela、BESS、Heat和Caprice测得的反质子/质子比符合较好，并对AMS-02实验进行了预测。
英文摘要：
Galactic Cosmic Rays (GCRs) are mainly protons confined in the galactic magnetic field to form an isotropic flux inside the galaxy. Before reaching the Earth orbit they enter the Heliosphere and undergo diffusion, convection, magnetic drift and adiabatic energy loss. The result is a reduction of particles flux at low energy (below 10 GeV), called solar modulation. We realized a quasi time-dependent 2D Stochastic Simulation of Solar Modulation that is able to reproduce CR spectra once known the Local Interstellar Spectrum (LIS). We were able to estimate the different behaviors associated to the polarity dependence of the Heliospheric modulation for particles as well as for antiparticles. We show a good agreement with the antiproton/proton ratio measured by AMS-01, Pamela, BESS, Heat and Caprice and we performed a prediction for the AMS-02 Experiment.
