  The AISHa ion source is an Electron Cyclotron Resonance Ion Source designed to generate high brightness multiply charged ion beams with high reliability, easy operations and maintenance for hadrontheraphy applications. The R&D performed by the INFN-LNS team during the 2019/2020 has allowed the improvement of the AISHa performances up to 20% for some of the extracted beams: both injection and extraction flanges has been improved and a movable electrode has been installed. The low energy beam transport has been equipped of an Emittance Measurement Unit (EMU), working through the beam wire scanners principle, for the measurement of the vertical and horizontal emittance of the beams of interest for hadrontherapy applications. Beam emittance has been characterized as a function of q/m and of the beam intensity to highlight space charge effects. If necessary, the beam wire scanners can be used for the characterization of the beam shape. The perspectives for further developments and plasma diagnostics will be also highlighted.

  The 2.45 GHz Electron Cyclotron Resonance Ion Source (ECRIS) has been indigenously developed. This development of ECRIS aims to provide high brightness, stable, and reliable D+ ion beam of 20 mA beam current in a continuous (CW) mode operation for an accelerator-based D-T neutron generator. The ECR ion source setup consists of a microwave system, a magnet system, a double wall water-cooled plasma chamber, a high voltage platform, a three-electrode ion extraction system, and a vacuum system. The ECR ion source test setup is installed, and the deuterium plasma is generated. A three-electrode extraction system is designed and fabricated for the ion beam extraction. A ~10 mA deuterium ion beam is extracted from the ECR ion source. The paper covers the detailed experimental setup of ion beam characterization and diagnostics used for measurement of beam profile, beam current, and beam emittance measurements. It also covers the latest results of beam emittance measurements.
