ABSTRACT:
Deflection unit (5) in which field-conducting elements (9,10) are provided between the field deflection coil (8) and the line deflection coil (7) so that a good level of astigmatism as well as an acceptably small coma error and a reduced EW frame distortion are obtained. In order to prevent that the field-conducting elements (9,10) from having a detrimental influence on the ten-pole field generated by the field deflection coil (8), each of the said elements is formed as a slightly curved plate having a central portion (15) on which two limbs (17,19) extending substantially transversely to the axis (Z) of the annular member (6) are formed.
