Description
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.
