The Study Of Electrons Transmission In The Straight Tube And Cone Tube Glass

This paper mainly studies the electronic guide in glass capillary effect, is the second division of the ion beam in lanzhou university laboratory ion transport platform. On ion transport platform, generated by the electron gun electronic after lead to voltage acceleration, the slit and focusing device on the electron beam collimation, bombardment to the installation in 3 d translation,2 d rotation target on capillary glass tube, we use ion transport platform at the end of the adjustable Angle of the MCP detect different direction of electronic counting, through the analysis of the under different deflection Angle of MCP and detection of glass capillary electronic distribution and intensity to study guide in the capillary effect, In this experiment, using the electronic energy between a few hundred to several thousand electron volts, exposure to the target frame beam spot size control for 1 mm * 1 mm.
