摘要: Abstract The cryo-condensation pump used in EAST-NBI is composed of panels cooled by liquid helium and radiation shields nitrogen. transmission probability has great influence on the performance pump. Monte-Carlo method applied to simulate trajectories deuterium molecules study effects structure probability. By adding imaginary walls, distribution positions flying directions presented. results indicate that uniformity direct factor
