The foremost requirement for a Hi-Vision camera tube is high resolution. To meet this requirement, 1.5-inch vidicons, 2-inch return beam vidicons, and 2-inch return beam saticons (RBS tubes) were employed in the early research on Hi-Vision.1 While those camera tubes contributed significantly to the success of system experiments as the signal sources for the image evaluations and instrument testing, their performance was not sufficient for commercial cameras. To meet this new requirement, a 1-inch MM type (Magnetic field-converging, Magnetic field-deflecting) camera tube called DIS (Diode-gun Impregnated-cathode Saticon) was developed.
