Feasibility of Using a Small Angle Neutron Scattering Beamport with an eVinci Hybrid University Research and Power Reactor

公开 Deposited

This project is a preliminary investigation into using the eVinci micro power reactor as a neutron source for a university-based Small Angle Scattering (SANS) instrument. This was done by using the program McStas to simulate neutron scattering. Due to time constraints as well as neutron intensity and budget concerns, thermal neutrons were used. Due to the use of thermal neutrons, single crystal monochromatization was used by simulating a BeO crystal mosaic. The sample used to determine the viability of the setup was SANS_spheres2, and this gave us a Q range from approximately 0.1-0.01 Å-1. Although these early results were promising for a lab-based SANS instrument, further investigation relating to more accurate intensity and crystal simulations must follow our work.
