Numerical study for the effect of angle between inner wall of Wehnelt electrode and its axis on beam dynamics in a thermionic electron gun by Hanyu Gao, Guoquan Ding, Xin Zhou, Dongbo Chang, Ying Tian, Mengxiang Dang

“…The results indicate that a change in α causes a variation in the potential on the axis and its first and second derivatives to the axial distance, which in turn causes changes in the beam current and emittance and the radius and position of the beam waist; however, it has no significant effect on the kinetic energy of the electrons. When 75° < α ≤ 90°, the beam cannot be focused effectively. …”

Investigating the Effect of Preimpact Energy Dissipation on Coefficient of Restitution regarding the Slope-Boulder Interaction by Ran Bi, Shaoying Li, Gou Liu, Jianxi Ren, Yongjun Song

“…The results show that (1) as the inclination of initial velocity, higher rebound height, and the declining normal coefficient of restitution occur, a determinable linear function could demonstrate relationships among energy dissipation and all coefficient of restitution; when initial velocity exceeds 5 m/s, the recovery ability shows and produces an increasing trend with respect to the variation of kinematic coefficient of restitution and kinetic energy coefficient of restitution. (2) As the surface material varies, slope hardness and rebound ability influence normal coefficient of restitution, and the surface roughness and rotation feature dominate tangential coefficient of restitution; considering preimpact slope and boulder interactions, four types of coefficient of restitution follow declining trend with different material sequence. (3) Slope angle affects normal coefficient of restitution, and tangential coefficient of restitution relatively descends 18% and inclines 10% when the angle ranges from 30° to 75°; regarding preimpact moving status, it differs from bounce times. …”
