Study of electron emission in the reaction of highly charged ions with solid surface

众所周知，高电荷离子，即被剥夺了许多电子的原子，在与固体表面的反应（碰撞）中导致许多电子的发射。发射出的电子数远远超过高电荷离子的电荷数。在某些情况下，电子是自旋极化的，这意味着自旋（与旋转陀螺的轴方向相关）沿某个方向排列。为了研究这种现象，我们已经建立了一个自旋偏振仪。在本研究中，我们设计并制作了一个独立的极化电子束源，用于极化仪的校准。

It is well known that a highly charged ion, that is an atom deprived of many electrons, causes emission of many electrons in the reaction(collision) with solid surfaces. The number of emitted electrons exceeds well beyond the charge number of highly charged ions. In some cases, the electrons are spin-polarized, which means that the spin(associated as the direction of the axis of spinning top) is aligned in a certain direction. To investigate this phenomenon, we have already built a spin polarimeter. In this study we designed and constructed a separate polarized electron beam source for the purpose of calibrating the polarimeter.
