Abstract
The cyclotron CIME is presently used at GANIL for
the acceleration of SPIRAL1 radioactive beams. One of
the goals of the SPIRAL2 project is to produce, postaccelerate
and use in the existing experimental areas
much higher intensity secondary beams induced by
uranium fission like neutron-rich krypton, xenon, tin
isotopes, and many others. Intensity may reach 1010 pps.
Specific developments are needed for secondary beam
diagnostics. Improvement of mass separation is also
necessary, and the Vertical Mass Separator (VMS) is
specially developed for this purpose.
However, the main concern is related to the high
radioactivity linked to RIB high intensity. Safety and
radioprotection issues will require modifications of the
installation with special care for the maintenance of the
cyclotron. The experience of the SPIRAL1 beams, in
terms of beam losses and equipment contamination, is
especially useful to define the necessary modificationsIMP;Chinese Academy of Science
