Abstract
A raster distortion corrector for a cathode ray tube includes magnetically permeable corrector pieces that are located on opposite sides of the deflection yoke. A part of each corrector piece is located within the external field of the vertical deflection coils and presents a low reluctance path to the external field flux. The flux is directed via a flux channelling arm of each corrector piece to a field shaper that causes a distortion correcting field to be formed between the corrector pieces. The flux channelling arms are formed and located so that there is no significant interaction of the corrector pieces with the horizontal deflection field.
