The SPIRAL2 project is based on a multi-beam driver in order to allow both ISOL and low-energy in-flight techniques to produce Radioactive Ion beams (RIB). A superconducting light/heavy-ion LINAC capable of accelerating 5 mA deuterons up to 40 MeV and 1 mA ions up to 14.5 MeV/u is used to bombard both thick and thin targets. These beams could be used for the production of intense RIB by several reaction mechanisms (fusion, fission, transfer, etc.). In order to visualize the SPIRAL2 beam dynamics, several beam profile monitors are under development. Multiwire beam profile monitors (SEM) will be used on the driver and RIB lines, a non interceptive beam profile monitor (RGM) should be mounted on the LINAC diagnostics box and before the experiment facility, and a low intensity beam profile monitor (EFM) on the RIB lines. Signal acquisition from these monitors will be accomplished through new associated electronics which digitize 94 channels in a parallel system. Each channel integrates the current of the associated wire or strip and performs a current-voltage conversion. The dedicated GANIL data display software has been adapted for these new monitors.
