  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 BETA-NU angular correlation parameter in nuclear BETA
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 (6He1+) and the precision on
the V u d element of the quark-mixing matrix (35Ar1+ and 19Ne1+) deduced from
the mirror transitions dataset.
