Dr. IKEDA Yujiro, Former Director of the J-PARC Center and Senior Visiting Scientist at the RIKEN Center for Advanced Photonics

This award is given to individuals who have made outstanding contributions to the development of neutron science in Japan. The award was presented to Dr. IKEDA Yujiro, the former director of the J-PARC Center and currently a senior visiting scientist at the RIKEN Center for Advanced Photonics. Dr. IKEDA, who has been involved with J-PARC since its construction phase, passionately gave an award lecture on challenging events which he had worked with many people together for J-PARC.

Dr. WATANABE Masao of the Technology Development

This award is given to those who have made outstanding contributions to the technical development of neutron science. Dr. WATANABE Masao of the Technology Development Section received the award.
Dr. WATANABE and his colleagues have developed and matured the pulsed high-field magnet equipment from its initial development to a stage available to J-PARC users, in order to realize neutron diffraction experiments under high magnetic fields, which had been a longstanding problem in the neutron field, and from there have made numerous technological innovations that have spread to other neutron facilities around the world.

1. Dr. UETA Daichi of the Neutron Science Section

Dr. UETA Daichi of the Neutron Science Section received the award. Dr. UETA conducted neutron experiments on cerium, which exhibits a wide variety of physical properties, focusing on its magnetic properties. He observed magnetic properties, magnetic anisotropy and magnetic excitations in cerium-containing compounds, and clarified the reasons for the appearance of unique physical properties. These achievements are expected to play an important role in the new understanding of 4f electron systems containing cerium, which cannot be explained by conventional theories. He delivered the award lecture entitled 'Study of novel physical properties in Ce compounds'.

2. Dr. YAMASHITA Takayuki, Former Postdoctoral Researcher in the Neutron Science Section and Assistant Professor at Osaka University

Dr. YAMASHITA Takayuki, a former postdoctoral researcher in the Neutron Science Section and now an assistant professor at Osaka University, received the award.
Using TAKUMI, the engineering materials diffractometer at J-PARC, Dr. YAMASHITA studied the mechanism of high strength and excellent ductility of advanced structural materials expected to be used in a wide range of next-generation industries. He gave an award lecture on 'Appearance Mechanism of the Mechanical Properties in Advanced Structural Materials via Pulsed In-situ Neutron Diffraction'.
The award is given to young researchers under the age of 40 who have published outstanding research in neutron science.
