抄録

An apparatus which contracts or enlarges the spot of ion beam without energy dispersion is proposed. When two electric fields of sector type with the same field characterizing constant are oppositely combined in tandem and the source slit is placed at the focal point of the first field, then the image is focused at the focal point of the second field. The energy dispersion at the image position is cancelled out in the first approximation if the deflecting angles of two fields are equal even if the mean radii of them are different. Only the image is contracted or enlarged by the ratio of the radius of the first field to that of the second field.
The coefficients of the second order aberration of this apparatus are calculated in the case of cylindrical electric field and of spherica electric field. The total spread of the image due to the second order aberration may be reduced less than 1 micron at proper conditions in the case of cylindrical electric field with the deflecting angle of 45° and the contracting ratio 5.
