Abstract: An electron beam scanner has a broad surfaced target and an area cathode with control electrodes sandwiched therebetween for controlling the electron flow between the cathode and the target. The target comprises a transparent plate member having a phosphorescent coating thereon which emits light through the transparent plate in response to electrons incident thereon, electrons being passed from the cathode to the target through channels formed by alined apertures in the control electrodes. The surface of the control electrode directly opposite the phosphorescent coating on the target is light absorbent such that substantially all of the light passing through the target plate or reflected from the outer surface thereof is absorbed.
