The SPIRAL2 facility will extend the possibilities offered at GANIL to heavier radioactive beams, with much higher intensities : it will provide intense beams of neutron-rich exotic nuclei created by the ISOL production method. The extracted exotic beam will be used either in a new low energy experimental area called DESIR, or accelerated by the existing SPIRAL 1 cyclotron (CIME. The intense primary stable beams (deuterons, protons, light and heavy ions) will also be used at various energies for nuclear physics, as well as for neutron-based research and multi-disciplinary research, in dedicated caves called S3 and NFS. During year 2008, the decision has been taken to build the SPIRAL2 machine in two phases: - first phase including the driver accelerator and its associated new experimental areas (S3 and NFS caves), - second phase including the RIB production part, with the low energy RIB experimental hall called DESIR, and the connection to the GANIL existing facility for post-acceleration by the existing CIME cyclotron. The SPIRAL2 facility is now in its construction phase, with the objective of obtaining the first beams for physics during year 2014 with the first phase.

TRIUMF's ISAC is an ISOL-type RIB facility. RIB are produced in direct reactions of 480–500 MeV protons from TRIUMF's main cyclotron on thick targets in one of two production target stations. Like other such facilities, ISAC is only capable of serving a single RIB user at any given time, though simultaneous delivery of stable and radioactive beams to different experimental areas is possible. With the construction of ARIEL, the Advanced Rare-IsotopE Laboratory, ISAC will gain a second production front end. RIB will be produced by photofission on actinide targets using electrons from a new superconducting electron linac. This will give ISAC the ability to serve two RIB experiments concurrently with beams produced by different reaction mechanisms in separate target areas (with delivery of a third, stable, beam still possible). The shift from single-user to multi-user RIB operation will introduce significant new complexity to beam delivery, requiring new tools and techniques for beam time to be used efficiently. A first look at the potential operational requirements of a multi-user RIB facility will be discussed.

Nowadays cancer can be considered as one of the wide spread diseases all around the world. Radiotherapy is the clinical technique used in 40% of cancer treatments: nowadays about 40% of the 18000 particle accelerators running in the world are devoted to radiotherapy. Classical radiotherapy employs photons and electrons that damage not only the diseased cells but also the healthy ones. Hadrontherapy is a high-precision radiotherapy exploiting the depth-dose deposition characteristics of the hadron particles. The realization of machines for hadrontherapy is more challenging than for standard radiotherapy: while most of hospitals have a device for classical radiotherapy, the hadrontherapy needs a dedicated building with the needed technology for the hadron acceleration. The first hadrontherapy treatments have been performed in particle physics research centers clinically adapted; nowadays there are dedicated facilities designed and built as hadrontherapy centers. This paper will give an overview on the existing hadrontherapy centers presenting the technologic background that is at the basis of the hadrontherapy world.

Electron stripping process from heavy ion in material is a useful tool in accelerator complex to give higher charge state of the ion, allowing its effective acceleration. This process is competed with electron capture process and reach to the equilibrium charge state. Carbon foils is convenient for charge stripper but have short lifetime due to thermal stress and sputtering in the case of high power beam of heavy ion such as uranium. Gas is basically free from lifetime but gives lower charge state due to absent of density effect. Therefore, charge stripper especially for uranium beams at 10-20 MeV/u could be a bottle-neck problem in high power heavy ion facility such as RIBF, FRIB and FAIR. A charge stripper using low-Z gas (He or H2) is an important candidate to solve the problem because the high equilibrium mean charge states for the low-Z gas stripper are expected due to the suppression of the electron capture process. This presenation will describe the results for the develeopments and tests of He gas stripper for uranium beams at 11 MeV/u.
