Abstract
The surface conditions of a material, such as roughness and cleanliness, can significantly affect its electron yield, thereby influencing the amount of surface charging. This study aims to identify roughness parameters that correlate surface roughness to electron yield. Surface roughness and electron yield of aluminum samples were measured and compared. Four roughness parameters, namely Spc, Sdr, Sa, and Ra, were identified as effective in characterizing surface roughness. Understanding the correlation between surface roughness and electron yield is crucial for predicting the electron yield of a material with a specific roughness and developing effective mitigation approaches.
