Abstract : The experimental achievements and the results obtained so far with the LPCTrap device installed at GANIL are presented. The apparatus is dedicated to the study of the weak interaction at low energy by means of precise measurements of the – angular correlation parameter in nuclear decays. So far, the data collected with three isotopes have enabled to determine, for the first time, the charge state distributions of the recoiling ions, induced by shakeoff process. The analysis is presently refined to deduce the correlation parameters, with the potential of improving both the constraint deduced at low energy on exotic tensor currents (6 He 1+) and the precision on the V ud element of the quark-mixing matrix (35 Ar 1+ and 19 Ne 1+) deduced from the mirror transitions dataset.
