Abstract
PURPOSE: To enable to measure the angular distribution of electron flow easily, by measuring the beam current through the sequential emission of the electron flow having different emission angle emitted from the electron gun with the two stages of the polarization systems placed between the electron gun and the collective lens to the collective lens.
CONSTITUTION: The electron gun 1 consists of the filament 2, Wehnelt electrode 3 and anode 4. The electron flow from the electron gun 1 is collected with the first and second collection lenses 5, 6, control is made at the power supplies 7, 8, and the excitation of the lens 6 can be interrupted with the switch 9. The electron flow can be detected with the Farady cup 11 on the stage 10, and the signal is fed to the terminal Y of the X-Y recorder 13 via the amplifier 12. The deflection signals S1, S2 are fed to the two stages of the polarization systems 14, 15 from the deflection power supply 18, and a part of the signal S1 is fed to the X terminal of the recorder 13. After image forming the cross over image on the cup 11, the signals S1, S2 are suitably swept to obtain the distribution curve of emission electron flow.
