%X A 4nm thick amorphous Al 2O 3 electron transmission film at the input of MCP is fabricated by electrostatic film-posting technology, which causes no carbon contamination in inner channel surface. The relation between film posting and glow discharge of the gases is discussed, and the electron transmission and ion barrier effectiveness of electron transmission film at the input of MCP are measured. Results of the experiment show that a 4 nm thick amorphous Al 2O 3 electron transmission film is characterized by high electron transmission, ion feedback prevention.
