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. A brief presentation of the next steps is given.

IFMIF (International Fusion Materials Irradiation Fa-cility) is an accelerator-driven neutron source aiming at testing fusion reactor materials. Under the Broader Ap-proach Agreement, a 125 mA / 9 MeV CW deuteron accelerator called LIPAc (Linear IFMIF Prototype Accel-erator) is currently under installation and commissioning at Rokkasho, Japan, to validate the IFMIF accelerator. During the beam commissioning at 5 MeV which started in June 2018, the horizontal and vertical transverse emit-tance of a 2.5 MeV proton beam have been measured downstream of the RFQ for different machine configura-tions. Such measurements were done with an emittance measurement unit composed of slits defining a beamlet of 200 µm width, then of steerers and finally of a SEM grids monitor. In this paper, the process and the system are first described. The secondary electron emission of SEM-Grid wires is then estimated based on measure-ments and results are close to the usual rule of thumb. Finally, emittance measurements are presented and comparisons with beam dynamics simulations show good agreement.

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.

MYRTE (MYRRHA Research Transmutation Endeavour) performs research to support the development of the MYRRHA (Multi-Purpose Hybrid Research Reactor for High-Tech Applications) research facility, which aims to demonstrate the feasibility of high-level nuclear waste transmutation at industrial scale. MYRRHA Facility aims to accelerate 4mA proton beam up to 100 MeV. The accurate tuning of LINAC is essential for the operation of MYRRHA and requires measurement of the beam transverse position and shape , the phase of the beam with respect to the radiofrequency voltage with the help of Beam Position Monitor (BPM) system. MYRTE aims to qualify beam operation at 1.5MeV. Two BPMs were realized for MYRTE operation. This paper addresses the design, realization, and calibration of these two BPMs and their associated electronics. The characterization of the beam shape is performed by means of a test bench allowing a position mapping with a resolution of 0.02mm.
