(/b) and (ld) are one set each of the vacuum duct (2
) and generate a magnetic field to vertically and horizontally deflect the beam passing through the vacuum duct (c).

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

以上のような従来のステアリングコイルでは、コイルの
配置上、磁場の一様性が悪いという問題点があった。The conventional steering coil as described above has a problem in that the uniformity of the magnetic field is poor due to the arrangement of the coil.

この発明は、かような問題点を解消しようとするもめで

２−０．７の範囲にある。In the steering coil according to the present invention, the ratio between the spacing of a pair of racetrack-shaped opposing coils and the coil width is 0.
It is in the range of 2-0.7.

〔作用〕[Effect]

この発明においては、コイルの配置、寸法を特定したこ

and the coil width W ratio g/w=0. ! r~0.7 There is a difference. The same applies to coils (lb) and (ld). (C) is a vacuum duct.

ここで、直線部りが比較的長いレーストラック形のコイ
ルでは、発生磁場は主にコイルの直線部で決定される。Here, in a racetrack-shaped coil with a relatively long straight portion, the generated magnetic field is mainly determined by the straight portion of the coil.

In Figure 6J, the horizontal axis is the ratio of the coil spacing to the coil width, and the vertical axis is the magnetic field uniformity. This is a graph.

これよりコイルが比較的長いものにα＝閃、５ついては
ζ＝０．３；！ｒ〜０゜ｓｇ程度でｆの値がＯに近く、
磁場の一体性が高いことがわかる。For those with relatively longer coils than this, α=Flash, and for 5, ζ=0.3;! When r~0°sg, the value of f is close to O,
It can be seen that the magnetic field has high integrity.

また、α＝ｌの正方形に近いコイルでは、ζ＝０．６！
〜ｏ、ｂ　を程度で磁場一様性が高い。Also, for a coil close to a square with α=l, ζ=0.6!
The magnetic field uniformity is high at ~o,b.

ζは１以上であるため、互いに直交する２組のコイルを
同じ場所に配設するためには、コイル（ｌａ）〜（ｌｄ

) will be combined as parallels.
