ABSTRACT:
A storage cathode-ray-tube having a single off-axis flood gun is described including auxiliary coils defining electromagnets placed, one electromagnet on either side of the cathode-ray-tube to correct non-symmetrical geometry in optical representations produced on the fluorescent screen of the cathode-ray tube caused by interaction of the conventional principle electron beam under the control of electrical signals during storage operation.
