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

日光层中的高能粒子受到许多传输和加速过程的影响。银河系宇宙射线和其他高能粒子的强度受到日光层大尺度结构的调制。另一方面，在共转相互作用区、日冕物质抛射(CME)和其他太阳事件以及一般的太阳风中的微观过程影响高能粒子的通量和光谱。空间扩散和能量扩散由AlféNic、磁声或离子-声学湍流决定。我们将集中讨论与日冕物质抛射有关的三种高能粒子：1)在CME驱动的激波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)星际或内源拾取离子。为了更好地理解离子在内日光层中的传输和加速，在那里CME驱动的冲击被认为是相当强的，我们将分析目前可获得的CME驱动的激波在地球附近的三个群体的行为？S轨道。我们计划覆盖超热和高能离子的能量范围，以研究不同激波构型对不同来源粒子的注入和加速的影响。特别是，我们将研究CME驱动激波附近不同的湍流产生机制和不同类型的波-粒子相互作用。

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.
