Abstract

The secondary emission electron flow generated by the incident ions and electrons on the spacecraft surface changes with the change of the secondary electron emission coefficient. The influence of the secondary electron emission coefficient on the charging current and potential is verified by modeling and simulation. The surface material ITO (Indium tin oxide) used in spacecraft was studied. The results show that the secondary electron emission coefficient is related to the thickness of the material, and decreases with the increase of the material thickness. Therefore, the secondary electron emission coefficient can be affected by changing the thickness of the spacecraft surface material Controlling the charged state of spacecraft surface materials.
