AbstractA secondary electron emission model have been developed to simulate electron induced SEE from complex, textured surfaces for any material. In this paper, the model employs two simple geometries to simulate ion-textured copper surfaces. An exploration of nondimensional geometric parameters shows the effects that fiber characteristic lengths have in the reduction of true yield by capturing secondaries emitted from the underlying substrate. Sensitivity studies of fiber radius and surface properties show significant correlations between the true yield and these parameters.
