Abstract :
In this paper, Y2O3-Lu2O3 co-doped molybdenum secondary emission material were prepared by spark plasma sintering at 1480 °C for 5 minutes. the penetration depth of the primary electron were studied using Monte Carlo methods. Using first principles calculations based on the density functional theory, the secondary emission mechanism of the cathode were analyzed.
