Abstract
Accumulation of charge between neighboring image lines can be prevented in a television pick-up tube in which an image pick-up face is scanned along image lines by an electron beam when a comparatively small periodic deflection is imposed on the electron beam in a direction perpendicular to the image lines. To achieve this, a magnetic deflection element in the form of a saddle-shaped coil is disposed between the vertical deflection element of the television pick-up tube and the envelope of the electron gun.
