The abstract of the manuscript is as follows: Abstract: Jupiter’s poleward (Zone II) main aurora exhibits bi-directional electron acceleration; upward acceleration dominates but downward acceleration generates strong aurora. During Juno’s first perijove (PJ1), the upward acceleration manifested as narrow electron angular beams (within ~5 of the magnetic field) over the 30-1200 keV energy range of Juno’s Jupiter Energetic Particle Detector Investigation (JEDI). These beams can be simply connected (non-uniquely) to >10 to perhaps 100’s of MeV electrons that penetrated the radiation shielding of the camera head of the Magnetometer Investigation’s Advanced Stellar Compass (ASC). The most intense of those multiple MeV populations are shown to have been highly directional and propagating upwards. How auroral processes generate such beams is unknown. With azimuthal symmetry assumed (not demonstrated here), these beams provided >1026 s-1 of >30 keV electrons to Jupiter’s vast magnetosphere, a possibly critical and dominating source of energetic electrons to that region and ultimately to Jupiter’s radiation belts.

摘要：木星向极区（第二区，Zone II）的主极光呈现双向电子加速现象：向上加速占据主导地位，但向下加速过程亦会产生强烈极光。在朱诺号首次近木过境（PJ1）期间，向上加速现象表现为窄角电子束流（与磁场方向夹角约5°以内），其对应能段覆盖朱诺木星高能粒子探测器探测计划（Jupiter Energetic Particle Detector Investigation, JEDI）的30~1200千电子伏（keV）范围。这类束流可（非唯一地）简单关联至能量大于10兆电子伏（MeV）乃至数百兆电子伏的电子——这些电子穿透了磁强计探测计划先进星罗盘（Advanced Stellar Compass, ASC）相机头的辐射屏蔽层。其中强度最高的多例兆电子伏级电子群体被证实具有极强的方向性，且传播方向向上。极光过程如何产生这类束流仍属未知。假设存在方位角对称性（本文未对此进行验证），这类束流向木星广袤的磁层注入了每秒超过10²⁶个能量大于30千电子伏的电子，这可能是该区域乃至最终木星辐射带中高能电子的关键主导来源。
