13. Target RD for the JHF N-arena (Japan Hadron Facility, Neutron-Arena)

摘要

The Japan Hadron Facility (JHF) [1], Neutron Science Laboratory (N-arena) [1, 2] is a project that aims to buid a world-class pulsed-spallation eutron source (PSNS) at KEK. The N-areana will use a proton beam from a 3 GeV-200 #mu# A-25 Hz proton-synachrotron (0.6 MW for the first stage and 1.2 MW for the second stage) For the target system of the N-arena, a solid-metal-target is the main option, and all of the target-moderator-reflector-assembly (TMRA) is being optimized for it.
