The minimum size of crystal that can typically be studied using a laboratory single-crystal diffractometer is 50 × 50 × 50 μm³. The X-ray flux from a synchrotron source is expected to be 10⁶ times the intensity of a laboratory source. Calculate the minimum size of a cubic crystal that could be studied on a diffractometer by using this source. A neutron flux is 10³ times weaker. Calculate the minimum size of crystal that could be studied by single-crystal neutron diffraction.
