Through Development of the Cryogenic Hydrogen System for the Spallation Neutron Source in J-PARC

Abstract

I contributed to the development of a cryogenic hydrogen system for the spallation neutron source in J-PARC. It was verified through cryogenic tests that the cryogenic hydrogen system satisfied performance requirements. In May 2008, the spallation neutron source successfully provided the first cold neutron beam, which was cooled by the cryogenic hydrogen system. Through the development of the system, it was found that liquid and supercritical hydrogen had excellent cooling properties. I wish to investigate a hydrogen cooling system for superconducting and hydrogen energy systems.
