Web17 aug. 2024 · First, a suitable grid potential structure to allow the measurement of an ion beam in plasma was investigated. After this investigation, a helium ion beam was measured without the production of plasma. It was found that the helium ion beam current was significantly overestimated when an unoptimized potential structure was utilized. 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.
