The LPCTrap experiment: measurement of the $\beta$–ν angular correlation in $^{6}$He using a transparent Paul trap
Résumé
We report on the status of the LPCTrap experiment, devoted to measure the β–ν angular correlation in the pure Gamow–Teller decay of $^{6}$He. This measurement is motivated by the search for the presence of tensor type contributions to the weak interaction. The $^{6}$He ions are confined in a novel transparent Paul trap. The β particles and the recoil ions are detected in coincidence to deduce the angular correlation parameter. The commissioning run performed in 2005 has given the proof of principle of this experiment. Up to 10$^{5}$ coincidences were recorded during a second run in 2006.
