Abstract :
Secondary electron emission is one of the most fundamental problems in spacecraft charging. An accurate prediction of secondary electron yield at low-energy electron impingement has long been a challenging problem due to both the complexity of the process and the difficulty in carrying out accurate measurements in a vacuum chamber. This paper discusses a correlated modeling and experimental study to investigate the facility effects on secondary electron emission yield measurement in a vacuum chamber.
