Title:
ELECTRON TUBE
Document Type and Number:
Japanese Patent JPH09297055
Kind Code:
A
Abstract:
To obtain such a structure that can stabilize the orbit of electron accelerated and focused by an electronic lens and effectively suppress the generation of noises due to discharging.
A cathode electrode 3 constituting an electronic lens extends partly toward a stem 10 along an inner wall 502 of an insulation container 5 and its tip end becomes thinner toward the stem 10, so that the tip end of the electrode 3 is apart from the inner wall 502 of the container 5. Thus, the container 5 is prevented from charging, and the discharging together with light emission to the electrode 3 and the container 5 can be suppressed.
