通过对GaAs晶体产生极化电子束流的实验过程研究,着重对yo-yo过程中不同的实验参数对产生极化束流以及束流稳定情况的影响进行了分析,为获得稳定而持久的极化电流提供了有力的实验支持,并讨论了极化电流强度的可控性。
By studying the process of producing polarized electrons by the photoemission of GaAs, different experimental parameters on the generation and stability of the electron beam is discussed. A feasible way to generate stable beam of long duration is provided. There is also a discussion on producing polarized electron beam with controlled intensity.
