                          MODEL QID-900 Quadrupole Ion Deflector



        SIMION 3D Simulation                       Model QID-900

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:

       Merged ion-laser beam experiments

       Merged ion-neutral beam experiments

       Multiple beam line switching

       Separation of ions from molecular/atomic/neutral beam particles

       Separation of ions from photons

       Cluster deposition and ion spectroscopy

       Deflection of ions at either 90, 180 or 270 degrees

       Energy Filter

The model QID-900 is also available mounted in a vacuum chamber (model QID-900-H).
