A novel in-situ detector for use during Small Angle Neutron Scattering measurements

A neutron transmission detector has been developed at ISIS for use on the Small Angle Neutron Scattering instrument, SANS2D. The new transmission detector has a negligible effect on the SANS pattern. This means the SANS area detector and the transmission detector can be used simultaneously. The use of this detector has given rise to a more than 30% increase in measurement output during its first period of operation. The unique design could be used at other SANS facilities, where currently the transmission measurement is taken independently of the SANS measurement.
