| Abstract: | The experimental phenomena and the experimental data of electron beam electron charge mass ratio measurement were ana- lyzed. DS-Ⅲ type experimental device has been used to finish this measurement by using magnetic focusing method. The experiment of electron beam spiral cleared starting position uncertainty and the concept of equivalent starting position has been put forward. |
