— The trend towards slim CRTs requires deflection yokes (DYs) with an improved deflection sensitivity. We present a new method to improve the deflection sensitivity by 15–25% by filling the space between the ferrite core and deflection coils with a soft magnetic material. The effect was analyzed in terms of a simplified two‐dimensional model. These model calculations were confirmed by three‐dimensional simulations and by experiments on a DY design for the Philips 29‐in. Real Flat CRT.
