摘　　要：利用静电贴膜技术在MCP输入面制备了 4nm厚Al2 O3非晶态电子透射膜 ,此工艺不造成MCP通道壁内表面碳污染 .探讨了贴膜与气体辉光放电的关系 ,测量了MCP电子透射膜的电子透过特性和离子阻挡特性 .实验表明 ,4nm厚Al2 O3非晶态电子透射膜能有效地透过电子 。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.
