Ibaraki prefecture, the local government of the area for the J-PARC (Japan Proton Accelaror Research complex) site in Japan, decided to build a versatile neutron diffractometer (iMATERIA, IBARAKI Materials Design Diffractometer) to promote industrial applications of neutron beam research at J-PARC. iMATERIA was planned to be a high throughput diffractometer so that materials engineers and scientists can use this diffractometer like any other chemical analytical instrument in their materials development programs. It covers in d range 0.18 < d (Å) < 5 with Δd/d = 0.16 % for the high resolution bank, and covers 5 < d (Å) < 800 with gradually changing resolution at three detector banks (90 degree, low angle and small angle). Typical measuring time to obtain a ‘Rietveld-quality’ data set is several minutes with the sample size of a laboratory X-ray diffractometer. To promote industrial applications, we will establish a support system for both academic and industrial users who are willing to use neutrons but are not familiar with neutron diffraction. The analysis software is also very important for powder diffraction experiments, so we will also prepare a software package (Z-Code) consisting of a combination of several powder-diffraction software tools (Z-Rietveld, etc.), structural databases and visualization. The construction of iMATERIA was completed, as one of the day-one instruments for the J-PARC neutron facility.  Recent data of iMATERIA will be reported.
