The EXCYT project has successfully come to conclusion at the end of 2006. As a consequence a new facility for production and acceleration of radioactive ion beams is now available at Laboratori Nazionali del Sud, Catania. This facility is based on the ISOL method: in particular the primary beam is delivered by a Superconducting Cyclotron, while the secondary beam is post-accelerated by a Tandem. A low energy radioactive beam is also available at the exit of the pre-injector. The main features of the commissioning of the facility will be described. Details will be given on the characteristics of the diagnostic devices. Future development activities are related both to the operative features of the new facility and to the improvements and upgrading that are planned to be introduced in the near future. All of these subjects will be extensively discussed.

The GSI accelerator facility provides highly charged ion beams up to U⁹²⁺ at the energy of 400 MeV/u. These are cooled and decelerated down to 4 MeV/u in the Experimental Storage Ring. Within the Heavy Ion Trap facility HITRAP the ions are decelerated further down. The linear decelerator comprises a 108/216 MHz doubledrift- buncher, a 108 MHz-IH-structure, a spiral-type rebuncher, and an RFQ-decelerator with an integrated debuncher providing energy spread reduction. Finally the beam is injected with the energy of 6 keV/u into a Penning trap for final cooling. The decelerator is installed completely and first sections have been successfully commissioned. For commissioning of the individual sections different ion species, e.g. ⁶⁴Ni²⁸⁺, ²⁰Ne¹⁰⁺, ¹⁹⁷Au⁷⁹⁺ were used. Each section was studied with comprehensive beam diagnostics to measure energy, emittance, intensity, transverse profiles, and bunch structure of the beam. The report gives an overview of the beam dynamics, the decelerator structures, and some results of the different commissioning runs.

The Centro Nazionale di Adroterapia Oncologica (CNAO) is the first Italian center for deep hadrontherapy, namely an innovative type of oncological radiotherapy using hadrons. The CNAO machine installation is in progress and alternates with lines commissioning, started in the Summer 2008. The present paper reports about Beam Diagnostics (BD) choices, status and post-commissioning evaluation, as concerns the Low Energy Beam Transfer (LEBT) line monitors.

In order to provide several kilowatt stable ion beams for radioactive ion beam production, the Grand Accélérateur National d’Ions Lourds (GANIL) upgraded several devices. A High Intensity Transport (THI) safety system has also been studied in 1995 and validated in 1998. By monitoring beam losses all along the cyclotrons and lines and shutting down the beam in case of problem, this system allows accelerating and sending onto targets up to 6kW power beams (instead of 400W in standard mode). Beam losses diagnostics, the associated electronics and software will be depicted (principle, location) as well as the tuning method of the machine to reach step by step the needed power.
