Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To prevent a filament from receiving ion impact or being damaged by ions, by furnishing an ion suppressor electrode held at a positive potential in a position ahead of a beam formation electrode. SOLUTION: An electron shower device concerned is equipped with an ion suppressor electrode 6 held at a positive potential in a position ahead of a beam formation electrode 4. When any ion 10 is flying toward the filament 3, the ion 10 is expelled back to the space by the electric field generated between the second anode 7 held at the ground potential and the ion suppressor 6 held at positive potential. A thermion generated by the filament 3 is accelerated by the electric field between the beam formation electrode 4 and the first anode 5 and also the electric field between the first anode 5 and ion suppressor electrode 6, and is decelerated by the electric field between the ion suppressor electrode 6 and the second anode 7. The effect of preventing the ion impact is obtained remarkably with the rise of the voltage impressed on the ion suppressor electrode 6.
