The Centro Nazionale di Adroterapia Oncologica (CNAO) is the Italian centre for deep hadrontherapy, namely an innovative type of radiotherapy using hadrons. The wide range of beam parameters (i.e., energy and intensity) at patient level together with the advantages of hadron-therapy with respect to traditional radio-therapy nourishes the hopes for more effective patient recovery. After the LEBT and the RFQ commissioning, the IH commissioning is now in progress. First patients are expected to be treated in 2010. The present paper summarizes and evaluates the Low Energy Beam Transfer (LEBT) line commissioning, which has been carried out between July 2008 and January 2009. |

The positive ion injector for the PIAVE-ALPI complex consists of an ECR ion source placed on a high voltage platform. A 14.4 GHz ECRIS named Alice, designed and constructed at LNL in the early &##8216;90, reliably delivered gaseous beams to the Superconducting RFQ PIAVE for nuclear physics experiments until 2008. The requests for heavy ion beams of increased current and energy, needed to perform the experiments planned for the next years with the AGATA demonstrator, prompted us to upgrade our injector with a new ECR source capable of higher output beam currents and higher charge states. This activity started in 2008 and was completed at the beginning of 2009. A 14.5 GHz, SUPERNANOGAN type ECRIS built by Pantechnik, was installed in our refurbished high voltage platform in July 2008. The space available for maintenance in the platform was increased and a new lead shielding for X-rays has been set up. The water cooling circuits have been redesigned to deliver different fluxes and inlet pressures to the equipment mounted on the platform (plasma chamber, extraction electrodes, bending dipole and power supply). A new safety system has been implemented in order to cope with new and more demanding safety rules. A lot of attention has been paid to the optimisation of the injection line with new diagnostic devices for beam characterisation (movable slits, emittance measurement tools). Commissioning of the new source and injector with beams has started and first results will be reported. |

Physics that motivated the building of the LISE magnetic spectrometer, main ideas exposed in the scientific council of GANIL June 4th 1981 by M. Brian and M. Fleury, were: atomic physics studies with stripped ions and the study of new isotopes produced by the fragmentation of beams. The LISE line is a doubly achromatic spectrometer (angle and position), with a resolution better than 10-3. Since the first experiment done in 1984, several improvements of the spectrometer were performed: use of a achromatic degrader (1987, used for the first time in the world), building of the achromatic deviation and the Wien Filter (1990), building of a new selection dipole and associated vertical platform (1994), building of the new LISE2000 line (2001), use of the CAVIAR detector (2002), building of the CLIM target (2007). Despite an extreme international competition, the LISE spectrometer remains a world-leader equipment using more than 50 % and up to 90 % of the beam time available at GANIL. This paper presents the status of CAVIAR detector which consists of a MWPC dedicated to in flight particle position at the first dispersive plane of LISE. Since two years, intensive efforts were done with the objective to make available a “plug and play” detector for nuclear physic experiment. We will describe the system from MWPC up to acquisition system. As example few experimental results will be presented. |
