[en] Beam stability and reproducibility is of paramount importance in applications requiring precise control of implanted radiation dose, like in the case of hadron-therapy. The beam intensity over several weeks and months should be kept constant. Standard valves used usually in conjunction of ECR ion sources have the disadvantage of controlling the conductance, which can vary significantly with external conditions, like ambient temperature and inlet pressure of the gas. The use of flow-controllers is the natural way for avoiding these external constraints. In this contribution we present the results obtained using a new model of mass-flow controller in the Supernanogan source for production of C⁴⁺ and H³⁺ beams. The minimum flow with this system is 0.014 ml_n/min until 0.06 ml_n/min. Extremely stable beams (± 2.5%) without retuning the source over several weeks can be obtained. The reproducibility of the source tuning parameters can also be demonstrated. The paper is followed by the associated poster. (authors)

[en] The Van de Graaff accelerator at IRMM (Institute for Reference Materials and Measurements, Geel - Belgium) works since many years providing proton, deuteron and helium beams for nuclear data measurements. The original ion source was of RF type with quartz bottle. This kind of source, as well known, needs regular maintenance for which the accelerator tank must be completely opened. The heavy usage at high currents of the IRMM accelerator necessitated an opening about once every month. Recently, the full permanent magnet Microgan ECR ion source from PANTECHNIK was installed into a new terminal platform together with a solid state amplifier of 50 W, a dedicated dosing system for 4 gases (with respective gas bottles H₂, D₂, He and Ar), and a set of dedicated power supplies and electronic devices for the remote tuning of the source. The new system shows a very stable behaviour of the produced beam allowing running the Van de Graaff without maintenance for several months. The paper is followed by the associated poster. (authors)

[en] Laser-target acceleration represents a very promising alternative to conventional accelerators for several potential applications, from the nuclear physics to the medical ones. However, some extreme features, not suitable for multidisciplinary applications, as the wide energy and angular spreads, characterize optically accelerated ion beams. Therefore, beyond the improvements at the laser-target interaction level, a lot of efforts have been recently devoted to the development of specific beam-transport devices in order to obtain controlled and reproducible output beams. In this framework, a three years contract has been signed between the INFN-LNS (IT) and Eli-Beamlines-IoP (CZ) to provide the design and the realization of a complete transport beam-line, named ELIMED, dedicated to the transport, diagnostics and dosimetry of laser-driven ion beams. The transport devices will be composed by a set of super-strong permanent magnet quadrupoles able to collect and focus laser driven ions up to 70 MeV/ u , and a magnetic chicane made of conventional electromagnetic dipoles to select particles within a narrow energy range. Here, the actual status of the design and development of these magnetic systems is described.
