从异常宇宙线（ACR）到在共转相互作用区（CIR）中加速的粒子，各种各样的日球层离子群已经被观测和研究了几十年。人们普遍认为，太阳风是所有这些粒子群的来源，除了ACR，而冲击加速产生了观测到的高能粒子，包括ACR。对于ACR来说，很久以前就提出的来源是渗透到日光层深处的星际气体。最近的测量的成分和光谱的超热离子，主要是从太阳能电池，ACE和风，表明皮卡离子可能是一个重要的来源，不仅是ACR，但为其他日光层离子人口以及。特别是，新发现的“内源”拾取离子可能是在内日光层中加速的粒子的重要来源，也可能是ACR C、Mg、Si和Fe的种子材料。此外，无处不在的高温...
A variety of heliospheric ion populations—from Anomalous Cosmic Rays (ACRs) to particles accelerated in Corotating Interaction Regions (CIRs)—have been observed and studied for several decades. It had been commonly assumed that the solar wind was the source for all of these populations, except for the ACRs, and that shock acceleration produced the energetic particles observed, including the ACRs. For the ACRs the source that had been proposed a long time ago was the interstellar gas that penetrates deep into the heliosphere. Recent measurements of the composition and spectra of suprathermal ions, primarily from Ulysses, ACE and Wind, indicate that pickup ions are likely to be an important source not only of the ACRs but for other heliospheric ion populations as well. In particular, the newly discovered “Inner Source” pickup ions may be a significant source for particles accelerated in the inner heliosphere and may also be the seed material for ACR C, Mg, Si and Fe. Furthermore, the omnipresent supratherma...
