The model QID-900 deflects the incoming positive or negatively charged ion beam at 90 degrees in a two-dimensional electrostatic quadrupole field*. The quadrupole field is set up using a combination circular electrode and shim electrodes to produce hyperbolic equipotentials. A set of entrance and exit einzel lens assemblies correct any 2-dimensional focusing of the ion beam through the quadrupole. Some possible applications for the model QID-900 include:<\/p>\n
