Abstract
A high-performance deflection yoke providing deflection of an electron beam in a CRT at high rates at high deflection angles. The high-performance deflection yoke includes a heat sink contacting the deflection yoke coils to remove the heat produced in the deflection yoke due to core losses and heat produced in the deflection coils due to resistive losses. The heat sink minimizes induced eddy currents and comprises fine wire elements, interwoven and/or in juxtaposition with the deflection coils, wherein the heat created within and picked up by the deflection coils is transferred to the heat sink for dissipation. By minimizing power lost in the heat sink due to inductive heating of the metallic components thereof, the heat sink according to the present invention provides a high-performance deflection yoke having low inductance, high power performance not heretofore practically realizable.
