abstract = {{Construction of a new accelerator is always an opportunity to face challenges and make new developments. The BPM diagnostics installed in the SPIRAL2 linac and the associated instrumentation are part of these developments. BPM instrumentations are, of course, used to measure positions and phases of ion beams but also transverse shapes, called ellipticity, as well as the beam velocity. Specifications involve knowing and calculating the sensitivities in position and in ellipticity as a function of the beam velocities. These impose small amplitude differences between channels, which require precise calibration of electronics. This paper describes the modelling and analysis of the BPM behaviour according to the beam velocity, the technical solutions, modifications and improvements. An analysis of the results and evolutions in progress are also presented.}},
