Description

The development of plasma diagnostics devoted to compact ion sources is being one of the main efforts of INFN-LNS ion source group for a decade. Indeed, the use of the brute force can lead to improvements in ion sources’ performances only if accompanied by a proper understanding of the plasma physics processes within the ion source. The key goal of plasma diagnostics in compact ion sources is the volumetric knowledge of the electron energy distribution function (EEDF) and the on-line evaluation of the plasma composition. This information will allow tuning EEDF to maximize the generation of the desired ion. Moreover, development of time resolved diagnostics has given precious information about the strategy for decreasing the beam ripple and increasing the operability domain of ion sources.
The paper will introduce the most relevant diagnostics developed in the last ten years at INFN-LNS (optical emission spectroscopy, volume and space resolved X-ray diagnostics, RF and Langmuir probe diagnostics, interfero-polarimetric diagnostics) together with the main experimental results they have permitted to attain.
Particular relevance will be also given to the perspectives and next goals of plasma diagnostics’applications.
