	The SPIRAL2 88 MHz CW RFQ is designed to accelerate light and heavy ions with A/Q from 1 to 3 at 0.73 MeV/A. The nominal beam intensities are up to 5 mA CW for both proton and deuteron beams and up to 1 mA CW for heavier ions. The design foresees almost 100% transmission for all ions at nominal beam current and emittance. Beam commissioning of the RFQ and linac cool down started already. The specifications have been achieved within the measurement precision for the different ions accelerated yet. This paper describes the beam commissioning strategy, the measurement results in both transverse and longitudinal planes and the success-fully first cryogenic tests of the linac.

	Beam dynamics of the MEBT and Superconducting Linac in the SARAF accelerator are being finalized. A strategy for beam tuning implementation is applied to this section, leading to specifying the complete set of error tolerances / beam measurements / correctors. A systematic and precise methodology in several steps is applied, leading to fairly distributing the error budget, from which correction schemes are studied, allowing to determine the necessary beam measurements and correctors.

	The SARAF MEBT and Super Conducting Linac (SCL) transport and accelerate deuterons or protons from the RFQ to the final energy. In this report, beam dynamics studies for this section are described. A rational distribution of the different roles of the MEBT leads to defining its necessary quadrupole/rebuncher composition. This allows easy beam re-tuning following changes from the RFQ or the SC Linac. After observing evidences of beam losses mainly due to phase unhooking, efforts have been dedicated to enlarge the SCL longitudinal acceptance. A combination of cavity field phases is found so that the required final beam energy is also fulfilled.
