Abstract
A cathode ray tube electromagnetic deflection unit comprising a support (4) having a flange (8) at its constricted end (5) which has a tangential groove into which radial grooves (14) merge. Two sets of deflection coils (18, 19) are wound on the support (4), the turns thereof running through the radial grooves (14) and the turns of one set bending into the tangential groove. The coils of the coil system 18 are for line deflection, and the two halves thereof are wound in the opposite winding sense and are energized during operation in such a manner that the highest voltage in both coils occurs at the coil turns adjacent plane of separation between the two coils and the lowest voltage occurs at the coil turns most remote from such plane of separation.
