Construction of High Power Pulsed Spallation Neutron Source

Abstract

This is a note written about the commend given to me by the Japanese society neutron science in 2024 on achievement of construction to operation of the pulsed neutron source at J-PARC. Addressing the most important events starting with ASTE collaboration to confirm a spallation neutron source with Hg target, how we have performed the construction of neutron source in largest scale never ever experienced. Appreciating, and fighting with critical addresses from Neutron Technical Advisory Committee, we have arrived at great completion of it. Note that all views are given from my personal view.
