Here we describe two neutron powder diffractometers, iMATERIA and SHRPD, at the Materials and Life Science Experimental Facility in J-PARC. iMATERIA (IBARAKI Materials Design Diffractometer) has been constructed to be a high throughput versatile diffractometer enabling materials scientists to use it like a chemical analytical instrument in their material development processes. Typical measuring time to obtain ‘Rietveld-quality’ data is several minutes for the sample size of laboratory X-ray diffractometer. On the other hand, SHRPD (Super High Resolution Powder Diffractometer) has been constructed by J-PARC to promote the best science using the best resolution in the world (Δd/d=0.03%) . Two instruments will be ready by the Day-One.
