A simple double-focusing electrostatic ion beam deflector

Savin, Daniel Wolf; Kreckel, H.; Bruhns, H.; Miller, Kenneth; Davis, A.; Wahlin, E.; Hockh, S.

We have developed an electrostatic, double-focusing 90° deflector for fast ion beams consisting of concentric cylindrical plates of differing heights. In contrast to standard cylindrical deflectors, our design allows for focusing of an incoming parallel beam not only in the plane of deflection but also in the orthogonal direction. The optical properties of our design resemble those of a spherical capacitor deflector while it is much easier and more cost effective to manufacture.
