Abstract

PURPOSE: To reduce the magnetic field produced by eddy current by making a notch for reducing the eddy current in radial pole piece mounted in cup body fixed at the tip of electron gun.
CONSTITUTION: Cup body 19 of such as stainless steel fixed at the tip of three electron guns arranged in delta have three openings 20 in side wall and the inner space is partitioned into three sections by non-magnetic metal shield 21 having Y-shaped cross-section, while radial pole piece pairs 22W24 are inserted through the opening 20. Many laterally extending elongated notches 25, 25' are formed in multi-stages in the opening 20 and the pole pieces 22W24. Consequently the eddy current flowing through the pole piece and cup body can be reduced thereby the field produced by eddy current can be weakened and corrective field can be produced accurately.
