- Abstract
Based on semi-classical theorem, Combining the particular surfaces shape of secondary electron emission in hall thrusters working chamber, and movement characteristics of the electrons(direction of motion, kinetic energy), the procedure of secondary electron emission in the particular incidence are analyzed. the approximate relation between incidence angle and secondary electron emission coefficient are Calculated according to escaping depth of secondary electrons and kinetic energy of primacy. The shape factor is firstly put forward. And further the secondary electron emission coefficient in a working chamber are deduced, the results are also analyzed and discussed.
