Neutron Source Development with Watanabe-sensei

Abstract

Moderator development from KENS to J-PARC was performed with Watanabe-sensei. A solid methane moderator was equipped at KENS as the first cold neutron source at pulsed neutron source dedicated to neutron scattering. A grooved methane moderator was also used at KENS. For the J-PARC neutron source, proton energy, moderator type and so on were decided. His wide and deep knowledge from science to engineering made construction of the J-PARC neutron source successful.
