| Abstract Scope |
We conducted feasibility studies for a Small-Angle Neutron Scattering (SANS) diffractometer at the MIT Nuclear Reactor (MITR). SANS is a critical technique for studies of materials, but three SANS diffractometers in the US are severely oversubscribed and require months of waiting time thus crippling projects and making it very difficult for students to include SANS in their thesis research. One way to increase capacity is by making SANS instruments shorter with the help of focusing optics. That would enable building additional instruments at user facilities, university reactors and future compact neutron sources. Our ray-tracing show that a 6-m MITR SANS will achieve Qmin ~ 4 × 10-3 Å-1 and the flux on the sample of 2×104 n/cm2/s, corresponding to the low-end boundary of SANS instruments. Measurements taking minutes at ORNL will take hours at MITR, but longer measurements are often preferable to months of waiting for the beamtime. |
