Ibaraki prefecture, the local goverment of the area for J-PARC site, was decided to build a versatile neutron diffractometer (IBARAKI Materials Design Diffractometer) to promote a industrial application for neutron beam in J-PARC. This diffractometer is planned to be a high throughput diffractometer so that materials engineers and scientists can use it like the chemical analytical instruments in their materials development process. It covers in d range 0.18 
d (
) 5 with 
= 0.16% at high resolution bank, and covers 5 d () 800 with gradually changing resolution at three detector bank (90 degree, low angle and small angle). Typical measuring time to obtain a "Rietveld-quality" data is several minutes with the sample size of laboratory X-ray diffractometer. To promote industrial application, a utilization system for this diffractometer is required. We will establish a support system for both academic and industrial users who are willing to use neutron but have not been familiar with neutron diffraction. The construction of this instrument was already begun and will be compleated in the beggining of 2008, as one of day-one instruments for J-PARC.

Ibaraki prefecture has started to construct IBARAKI biological crystal diffractometer for industrial use at MLF, J-PARC. It is designed to achieve the efficiency which is more than 50 times larger than the present high performance diffractometer BIX-4. To realize this performance, the diffractometer will be installed on a coupled moderator has more intense peak but wider pulse shape than a decoupled one. It is expected that some neighbor Bragg spots will overlap partially each other along the time axis. The overlapping of Bragg spots should be considered for optimization of design parameters and it is necessary to de-convolute the overlapped spots. The three original simulation programs of TOF diffraction data with designed parameters of the diffractometer were developed to obtain information of spot-overlapping, completeness of Bragg spots and spot profiles along the time axis. The consideration of important designed parameters will be reported based on the simulation results.
