A high aspect ratio cathode-ray tube (CRT) including a luminescent screen ( 28 ), an aperture mask ( 30 ) configured for transverse scan, an electron gun ( 32 ) and a magnetic deflection yoke ( 34 ). The electron gun ( 32 ) and the magnetic deflection yoke ( 34 ) are positioned so that the electron beams generated in the gun ( 32 ) scan a rectangular raster across the luminescent screen parallel to the tube minor axis (tranverse scan) to improve the current requirements for the magnetic deflection yoke ( 34 ).
