ABSTRACT:
An evacuated envelope having a plurality of parallel channels extending along and between spaced front and back walls. Each channel contains a plurality of parallel beam focusing guides, each of which is adapted to receive a beam of electrons at one end of the channel and confine the electrons in the beams as the beam flows through the focusing guide and to selectively deflect the beam toward a phosphor screen on the front wall of the envelope at a plurality of points along the channel. At each side of each channel is an electrode which extends from the front wall to a point spaced from the beam focusing guides. The electrodes are electrically connected to the phosphor screen and with the focusing guides serve to create an electrostatic field which fans out the paths of the electron beams emitted from the focusing guides so as to spread out the beams across the entire lateral dimension of the channel.
