(a) Simulated diffraction from Ewald onto a 4π spherical detector located 300 mm from the sample. The large number of Bragg peaks stimulated by such a large unit cell can be visualized. (b) Diffraction recorded on a single high-resolution SNS Anger camera at a 2θ angle of 90° is shown for Ewald. (c) A close-up of a simulated Bragg peak with Dmin = 2.0 Å is shown for Ewald and MaNDi. The Bragg peak produced from Ewald is composed of 541 neutron counts compared to 10 from MaNDi, highlighting the ability of Ewald to collect meaningful data on crystal volumes of 0.01 mm3 and below. |
