The electron gun includes a plurality of electrodes including a focus electrode (G5). The tube neck is adapted for receipt of a surrounding scan velocity modulation coil (54, 56) at a location thereon. The focus electrode includes two spaced parts same focus voltage (VFOCUS). The space (45) between the parts is surrounded by the neck location for the coil.
