论文摘要
在（前） - 星际环境中，灰尘和沙粒定期碰撞。在这些事件中，它们电力充电和排放。在这项工作中，我们研究了宇宙辐射是否对几分钟的时间尺度上的平衡电荷状态有任何影响。我们开发了一个实验，该实验是在平流层球囊的上升期间进行的。随着海拔高度的增加，辐射活性增加了54倍。但是，我们发现晶粒电荷的降低只有高达30％。这意味着，电荷调节过程从地球上的雷暴，在行星形成的早期阶段到短时间的颗粒表面上的颗粒运动，本质上是由于宇宙辐射的直接影响而受到了不受阻碍的。
In (pre)-planetary environments, dust and sand grains regularly collide. They electrically charge and discharge during these events. In this work, we study if cosmic radiation has any influence on the equilibrium charge state on timescales of minutes. We developed an experiment that was carried out during the ascent of a stratospheric balloon. With increasing altitude, the radiation activity increases by a factor of 54. However, we found only a very minor decrease in grain charges of up to 30%. This implies that charge-moderated processes from thunderstorms on Earth, over early phases of planet formation to particle motion on the Martian surface on short timescales essentially proceed unhindered from a direct influence of cosmic radiation.
