摘要: 本文討論了用邊界元法計算、分析帶屏蔽簡鞍形偏轉(zhuǎn)線圈的場分布,分析了法伊(D.M.Fye,1979)模型應(yīng)用的局限性。本文用馬克勞林級數(shù)展開格林函數(shù),給出了偏轉(zhuǎn)線圈的場參數(shù)B0,B2,B4的解析表達式。文末用實例對計算結(jié)果與實測數(shù)據(jù)進行了比較。

Abstract: 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. -
