Transport of suprathermal and energetic ions in the heliosphere and their injection and acceleration at shocks driven by coronal mass ejections

高能粒子在日球层受到许多传输和加速过程的影响。银河宇宙射线和其他高能粒子的强度受到日球层大尺度结构的调节。另一方面，在旋转相互作用区域、日冕物质抛射（cme）和其他太阳事件以及太阳风中的微观过程一般影响高能粒子的通量和光谱。空间和能量的扩散是由阿尔夫萨奇、磁子或离子声湍流决定的。我们将重点研究与日冕物质抛射相关的三种高能粒子：1)在日冕物质抛射中加速的太阳风离子，2)先前在脉冲耀斑中加速的离子，例如3He和3)星际或内源吸收离子。为了更好地理解cme驱动的激波被认为非常强烈的内日球层中离子的输运和加速，我们将分析地球轨道附近目前可到达的cme驱动激波附近的三个种群的行为。我们计划覆盖超热和高能离子能量范围，研究不同激波构型对不同来源粒子注入和加速的影响。特别是，我们将研究cme驱动激波附近湍流产生的不同机制和不同类型的波粒相互作用。

Energetic particles in the heliosphere are affected by many transport and acceleration processes. The intensity of Galactic cosmic rays and other energetic particles is modulated by the large-scale structure of the heliosphere. On the other hand, microscopic processes in corotating interaction regions, at coronal mass ejections (CMEs), and in other solar events and in the solar wind in general influence the flux and the spectra of energetic particles. Spatial and energy diffusion are determined by Alfénic, magnetosonic or ion-acoustic turbulence. We will focus on three types of energetic particles associated with coronal mass ejections: 1) solar wind ions accelerated at CME-driven shocks, 2) ions previously accelerated in impulsive flares, e.g., 3He and 3) interstellar or inner-source pick-up ions. For a better understanding of the transport and acceleration of ions in the inner heliosphere, where CME-driven shocks are thought to be quite strong, we will analyze the behavior of the three populations in the vicinity of currently accessible CME-driven shocks near Earth¿s orbit. We plan to cover the suprathermal and energetic ion energy range to investigate the influence of different shock configurations on the injection and acceleration of particles of different origin. In particular, we will investigate the different mechanisms of turbulence generation and the different types of wave-particle interactions near CME-driven shocks.
