A high aspect ratio cathode-ray tube (CRT) including a lumincscent 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). |
