Neutron scattering facilities have, for many years, depended on the availability of ³He for a large fraction of their detector requirements. Within the last 2–3 years demand for ³He, driven largely by the US homeland security requirements, has lead to an unprecedented rise in the cost of ³He and its unavailability for all but the smallest of systems.

For neutron scattering facilities to function effectively it is thus crucial that alternative, cost effective detector technologies are developed. The Detectors Joint Research Activity (JRA) focuses on the development of two promising detector technologies which could alleviate the dire situation now facing the facilities as a result of the high cost and near unavailability of ³He. The main objective of this JRA is the development of detector technologies to replace ³He detector technology in neutron scattering applications.
