When an energetic, heavy ion hits a solid target such as silicon or glass, it creates a long and narrow cylinder of damage, the so-called ion track. It is believed by many, and since many years, that the ion track melts, if ever so briefly (for less than a nano-second). However, no convincing proof exist and that is a pity, because these ion impacts happen more often than most would think (ion beam processing, nuclear waste storage, cosmic ray interference). I am planning to provide exactly such evidence, and will explain how in my proposal.

当高能重离子击中固体目标（如硅或玻璃）时，它会产生一个狭长的圆柱形损伤，即所谓的离子径迹。多年来，许多人认为离子轨道融化，即使如此短暂（不到一纳秒）。然而，没有令人信服的证据存在，这是一个遗憾，因为这些离子碰撞发生的频率比大多数人想象的要高（离子束处理，核废料储存，宇宙射线干扰）。我正计划提供确切的证据，并将在我的建议中解释如何。
