We present an experimental plan to study the weak interaction by measuring the electron-neutrino angular correlation from radioactive β-emitter atoms, 6He being the first case. Radioactive atoms, produced by a neutroninduced reaction, will diffuse to an electron beam ion source that ionizes, bunches and then injects them into an electrostatic ion beam trap where the angular correlation will be measured. We have tested the trap with stable ions and found the storage time to be 0.6 to 1.2 s for different ions. We have also performed the production experiment for 6He with a production rate of - 105 atoms/s. We present the current status of this project and future plans.
