Description
The WITCH experiment aims to study a possible admixture of a scalar or tensor type
interaction in beta decay by determining the beta-neutrino angular correlation from
the shape of the recoil energy spectrum. The experimental set-up couples a double
Penning trap system to form a scattering-free radioactive source and a retardation
spectrometer to probe the recoil ion energy. The intensive commissioning of the
set-up is ongoing at ISOLDE (CERN). The layout of the WITCH set-up and results of
commissioning tests performed until now will be presented. Results of the data taken
during 2006 (two beam times with 124In) will be shown as well, presenting the first
recoil ion spectrum obtained. Finally, perspectives of the physics program will be
discussed.
