The 9th AONSA/The 2nd Neutron and Muon School Meet@MLF

Message from the Director, Neutron Science and Technology Center, CROSS

It has been six years since Comprehensive Research Organization for Science and Society (CROSS) was appointed by the Japanese government in April 2011 to be the Registered Institution for Specific Neutron Facility at J-PARC MLF for conducting user promotion services as a Registered Institution for Facility Use Promotion. MLF has shifted into the second phase of being demanded a lot of fruitful output from user experiments with the initial phase of construction and commissioning of leading-edge research facilities almost completed. At this occasion, I declare our Vision in order for the staff to reconfirm our original mission and to stand-up and pursue it as a single body. That is, by promoting the facility use of MLF, producing excellent output at MLF leads to scientific discovery and technical innovation, which might ultimately contribute to the societal evolution. To realize our Vision we lay down Guiding Principle for Action of seven entries as well. These entries are, fair and clear proposal selections, new users promotion, attentive user support, creating productivity, releasing the results, collaboration with scientists and research institutions throughout the country and abroad and human resource development.

Last year the shut-down caused by the cooling water leakage from the neutron target vessel (April and November 2015) reduced the number of the recruited proposals by half compared to the average. On the other hand, though the beam power was suppressed to 150-200kW with the spare neutron target vessel, the conditions of the accelerator and neutron beam source kept stable. The operation rate achieved over 90% and the operation days surpassed initially scheduled 7-cycle operation, 154 days in the fiscal year 2016. J-PARC MLF takes it essential to provide stable and reliable beam supply for users to conduct research without hindrance. Making further effort to provide 1MW rated power output, MLF staff will be diligently working hard to enhance the performance of the facility step by step.

Currently we have seven Public Beamlines at MLF. They are BL01(4SEASONS), BL02(DNA), BL11(PLANET), BL15(TAIKAN), BL17(SHARAKU), BL18(SENJU) and BL22(RADEN). Working in close collaboration with J-PARC Center (JAEA,KEK), CROSS will continue to be fully committed to the task of user support on the Public Beamlines. This includes providing technical information and specialists' advice; operating a fair and transparent proposal selection system; and, diligently supporting the experiments of the Public Beamline users. CROSS will strive to realize full potential of the Public Beamlines and to help facilitate further important scientific outcomes.

In order for CROSS and J-PARC to make further progress, keeping up with the rapidly developing science, and to answer the requests of facility users, we need your continued support and encouragement. I hope that you will not hesitate to give me comments, suggestions and constructive criticisms about any aspect of our activities.

I look forward to hearing from you and welcoming you on your next visit to J-PARC.
