The minimum size of crystal that can typically be studied using a laboratory single crystal diffractometer is 50 x50x 50 μm. 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.
