Title: Image converter and intensifier tube - uses target and additional electrodes for selective electron beam (de)focussing
Inventor: LIEB ALBERT
IPC: H01J31/50
Filed: 1974-06-12
Abstract: The image converter and intensifier tube has a large surface target electrode coupled across and electric resistor to the positive pole of the operating voltage source. A focussing electrode with an effective electron beam aperture is coupled to the target electrode via a resistor of such value so that the two electrodes function as an anode during the tube operation in the rated range of the target electron current. This effect is supported by alignment of the electron apertures of the two electrodes. In case of sudden impingement of a considerably higher target electron current, such voltage difference is effected between the two electrodes that they form an electrostatic lens defocussing the electron beam aimed at the target electrode.
