Abstract

Deflection system containing two deflectors of opposite field directions has been studied. It is shown that achromatic deflection can be obtained in such a system by changing the beam energy between the deflectors. In the assumption that the deflection angles are small, the achromatic condition is derived analytically. The numerical computation has shown qualitative agreement with the analytical formulae. The scanning achromatic deflection system with intermediate retardation of charged particles between two deflectors is discussed in detail.
