The experiment is approved and in preparation at the Spallation Neutron Source, at Oak Ridge National Laboratory, in Tennessee, USA. It is the last one in a series of four experiments needed to provide a self-consistent description of the hadronic weak interaction (HWI) using few-body systems alone. Beam time has been allocated, tentatively starting in the early Fall of 2014.
