摘要：
A deflection apparatus includes a pair of quadrupole arrangements for producing a pair of quadrupole fields in a beam path of an electron beam at different distances from a display screen. In an embodiment of the invention, the first and second quadrupole arrangements and a main deflection field producing arrangement cooperate to converge three electron beams, R, G and B, with one another.
