Notes

Abstract: When a transverse electric field between a pair of closely spaced slits is used to deflect an ion beam, the length of the field region along the beam axis directly affects the length of time required to make the transition between the beam's undeflected and deflected states. Using the SIMION™ 3D 7.0 ion optics simulation program, which calculates electrostatic fields via numerical solutions to Laplace's equation, the authors have modeled a set of deflection slits for fast-pulsing a keV ion beam. The authors used the electric fields calculated in the model to simulate ion flight through the deflection region. By establishing a condition for ion transmission to a downstream target and by starting ion flights at different positions along the beam axis in the electric field region, the authors have obtained the time dependence for the beam's transition from the undeflected to the deflected state on the downstream target, assuming negligible propagation times of the electric field through the deflection region. The authors compare the simulated deflection to the measured performance of a deflection system on a small Cockcroft-Walton accelerator. The authors also investigate simulated slit configurations that reduce the length of the fields along the beam axis, thus optimizing the pulsing mechanism.
