摘要： In a first method, a meander-shaped coil (20,21) is provided on each side of the mask (7) having apertures (9). The coil (21) is oriented perpendicularly relative to the coil (21). If a current flows through the coils (20,21) in the correct direction, a magnetic quadrupole is formed along the circumference of each aperture (9). In a second method, a holder (30,31) with permanent magnetic strips (32) is provided on each side of the mask (7). The strips (32) in the one holder (30) are oriented perpendicularly relative to the strips in the other holder (31).A coil 40 is provided around the holders 30 and 31 with which a decaying magnetic alternating field, is generated which initially drives the material of the mask (7) on both sides of the hysteresis curve into saturation. After the decay of said alternating field a magnetic quadrupole is present along the circumference of each aperture (9).

摘要： A cathode ray tube for displaying colored pictures of the post-focusing type. The color selection means are formed by a plate which is provided with a large number of apertures, which plate is provided on one side with a first plate of parallel strips of hard magnetic material provided between the rows of apertures. The color selection means are magnetized in a direction perpendicular to the plane of the plate so that a magnetic quadrupole is obtained in each aperture.
