Web30 okt. 2014 · Ion beam etching, or sputtering, is a technique conceptually similar to sandblasting, but using individual atoms in an ion beam to ablate a target. Reactive ion etching is an important extension that uses chemical reactivity to enhance the physical sputtering effect. Applications of IBM. WebIf 4 grids are utilised, the ion extraction and acceleration processes can be separated, permitting total potentials of up to at least 80 kV to be employed. This concept has been proved in an experimental programme at ESTEC, for which several special diagnostic instruments were designed and built to characterise the high energy ion beam.
