Beam Diagnostics for SPIRAL2 RNB

http://accelconf.web.cern.ch/AccelConf/d09/papers/proceed.pdfInternational audienceThe SPIRAL2 project is based on a multi-beam driver facility in order to allow both ISOL and low-energy inflight techniques to produce intense radioactive ion beams (RIB) in a new Facility. A superconducting linac capable of accelerating 5-mA deuterons up to 40 MeV is used to bombard both thick and thin targets. These primary beams will be used for the RIB production by several reaction mechanisms (fusion, fission, etc.) The production of high intensity RIB will be based on fission of uranium target induced by neutrons. These exotic particles will be produced, ionized, selected in a dedicated production building and transported to the existing CIME cyclotron for post acceleration. After this, they will be used in the present experimental area of GANIL. The construction phase of SPIRAL2 was officially started in 2005. The beam diagnostics for the production facility allow a pre-tuning with a stable beam followed by an extrapolation to the radioactive beam. Some diagnostic devices may also provide for equipment protections and for the safety systems. An overview is presented of the diagnostics which will allow tuning and control of the RIB in this new production facility
