The new SPIRAL 2 construction will be realized in two phases, for the first phase the construction started in January 2011 and will consists of the accelerator buildings with two experimental facilities S3 and Neutrons for science (NFS). The second phase is the so called production building where radioactive ions are produced through the ISOL (Isotope Separation On Line) method. The produced radioactive ion beams (RIBs) will be extracted and accelerated up to 60keV from the ion sources, after beam purification the beam will be driven in the secondary beam lines either to a new experimental facility DESIR (Decay, excitation and storage of radioactive ions) constructed during the second phase of the new installation or the RIBs will be charge breed to form multi-charged ions that will be driven to the existing GANIL facility and post accelerated in the CIME cyclotron. This overview article gives a description of the secondary beam lines, the foreseen beam diagnostics which will allow tuning and controlling the radioactive ion beams in the secondary beam lines constructed in the SPIRAL2 Phase 2.

	In order to produce high intensity exotic beams in the existing experimental rooms of the GANIL facility, the SPIRAL2 project is under development and under construction at GANIL. The first phase of the SPIRAL2 project consists to build a new accelerator composed of two sources, an ion source and a proton/neutron source, a RFQ and a superconducting Linac. The linac is designed to accelerate 5 mA deuterons up to 40 MeV and 1 mA heavy ions up to 14.5 MeV/u. A new electronic device has been developed at GANIL to measure phase and amplitude of pick-up signals and calculate the beam energy. The principle consists of directly digitizing the pick-up pulses by under-sampling. The Phase and amplitude of different harmonics are then calculated with a FPGA by an I/Q method before the beam energy calculation. This paper gives results of the peak-up tests in laboratory and the comparisons with simulations. The tests in laboratory and on the GANIL accelerator of an electronic prototype are shown and presented.
