THE DETERMINATION OF THE FIELD PARAMETERS OF SADDLE DEFLECTION YOKE WITH A FERROMAGNETIC SHIELD
带屏蔽筒鞍形偏转线圈场参数的确定

The analysis and computation of the field distribution of the saddle deflection coil with a ferromagnetic shield by the boundary element method are described, and the limitations of the model proposed by D. M. Fye (1979) is pointed out. The Green s function is expanded by the Maclaurin series, and the analytical forms of the field parameters B0, B2 and B4 are given. The results obtained agree well with the experimentally measured values.
