	The SPIRAL2 Facility at GANIL is based on the construction of a superconducting ion CW LINAC (up to 5 mA - 40 MeV deuteron beams and up to 1 mA - 14.5 MeV/u heavy ion beams) with 2 experimental areas called S3 and NFS. The building, the accelerator and experimental equipment studies started in 2009. For safety classified system using beam intensity monitoring, SPIRAL2 project system engineering sets up a specific reinforced process, based on V-Model, to validate, at each step, all the requirements (technical, nuclear safety, quality, reliability, interfaces…) from the functional specifications to the final validation. Since 2016, the main part of the safety devices is installed and is currently under testing. These tests which are pre-requisites to deliver the first beam will demonstrate that both functional and safety requirements are fulfilled. This contribution will describe the requirements (operation field, limitation of equipment activation¿), the technical studies, the failure mode and effects analysis, the tests, the status and results of the SPIRAL2 Machine Protection System using AC and DC current transformers to measure and control the beam intensity.

	The SPIRAL2 accelerator, built on the GANIL’s facility, at CAEN in FRANCE is dedicated to accelerate light and heavy ion beams up to 5mA and 40 MeV. The continuous wave accelerator is based on two ECR ion sources, a RFQ and a superconducting LINAC. The beam commissioning of the RFQ finished at the end of 2018. This paper presents the Diagnostic-Plate installed behind the RFQ, with all associated accelerator diagnostics. Diagnostic monitors, measured beam parameters, results are described and analyzed.

	The SPIRAL2 facility currently under commissioning at GANIL in France will deliver high-intensity up to 20MeV/n and 5mA light and heavy ions beams. SPIRAL2 beams are accelerated by a Radio Frequency Quadrupole (RFQ) and a LINAC fitted with 20 supraconducting cavities. A tuning of the SPIRAL2 LINAC relies mainly on Pick-up Beam Profile Monitors (BPM). 20 BPM are mounted inside the warm sections between superconducting cavities. They serve to measure a beam transverse position to center the beam, a phase to tune cavities and an ellipticity to adjust beam optics along the LINAC. The phase and ellipticity measurements require high acquisition accuracy of the BPM signals. This paper deals with an analytical study and CST code simulations of the BPM performed in order to compute correction coefficients for the ellipticity measurements. The results of calculations were compared with experimental ones obtained with two BPMs located on a ¿diagnostic plate¿ after the RFQ . Finally, the BPM acquisition chain was carefully characterized to identify its uncertainties and to ensure that it meets initial specifications.
