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.
