Neutron powder diffraction measurements of 0.9 mm3of mixture of deuterated brucite and pressure medium were conducted at pressures to 2.8 GPa, using an opposed anvil cell and a medium-resolution diffractometer at Japan Proton Accelerator Research Complex pulsed neutron source. Spurious-free diffraction patterns were successfully obtained and refined to provide all structural parameters including Debye–Waller factors. Tilting of hydroxyl dipoles of brucite toward one of the three nearest-neighbor oxygen anions was confirmed to be substantial at pressure as low as 1.5 GPa. By this application, technical feasibility to analyze such a small sample has been newly established, which would be useful to extend the applications of neutron diffraction at high pressures.

It is a great honor to write an article on J-PARC, the Japan Proton Accelerator Research Complex, for a special issue of Neutron News. Although we now have the J-PARC neutron source, JSNS (Japan Spallation Neutron Source), the road to it was never flat but very long, steep and rough. Hence, this is a good opportunity to give an account of the history of developments of pulsed neutron sources in Japan and the importance of international collaboration for the current achievements.

Information about the papers discussed at several meetings on neutron research is presented. Topics include the advances in energy-selective neutron imaging, neutron analysis and scientific applications of techniques of polarized neutrons. The meetings feature several persons including Rector Magnificus Karel Luyben, Egbert Balsma and Theo Rekveldt.

Involvement of IPNS in the Spallation Neutron Source, a multilaboratory construction project funded by the U.S. DOE; Information on data acquisition system used in IPNS instruments; Diffractometers used as instrument suite.

Reports on the GEM general materials diffractometer project at ISIS pulsed neutron source. Aim of the project; Range of materials that is being made on the GEM instrument; Objectives of the GEM design; Considerations to the design of the diffractometer.

The author discusses the European Spallation Source Project (ESS), a long pulse spallation source that will be the world's most powerful source of neutrons. The author noted that ESS will be built in a way that governments can decide later to increase its power and add more target stations as the future scientific need arises. It was mentioned that ESS-I organization will continue to support all regions and governments that aspire to host ESS with the exchange of information and coordination.

The article discusses the highlights of the 9th New Opportunities for Better Use Group Software (NOBUGS) conference organized by the ISIS pulsed neutron facility and Diamond Light Source held at the Rutherford Appleton Laboratory in Oxfordshire, England. The NOBUGS conference aims to promote collaboration between research facilities and provide an opportunity for scholastic exchange. Discussions centered on cyborg experimentation and the uncertainty linked to numerical computation.
