FY2024 Kumagai Memorial Award for Vacuum Science Paper of the Japan Society of Vacuum and Surface Science
The 2024 Kumagai Memorial Award for Vacuum Science Paper in the Japan Society of Vacuum and Surface Science was presented to Dr. KAMIYA Junichiro of the Accelerator Division as the author of a paper that has made a significant contribution to the advancement and development of vacuum science.
Dr. KAMIYA conducted research into vacuum and material surfaces with the aim of realizing further ultra-high vacuum in accelerators and other components. He clearly showed that heat treatment of stainless steel, the material of the components, in a high vacuum, known as vacuum firing, can reduce the gas emissions from stainless steel vacuum chambers.
Furthermore, he succeeded in elucidating the mechanism by which vacuum firing causes surface modification that reduces hydrogen gas emissions from stainless steel and prevents the adsorption of other gas molecules, which are also sources of gas emissions.
There was no awardee in 2022 or 2023, and Dr. KAMIYA was selected for the first time in three years and gave an invited talk on the award at the Annual Meeting of the Japan Society of Vacuum and Surface Science in Fukuoka Prefecture.
