Development status of 30 MeV cyclotron-based neutron source in Korea

Abstract

KAERI has developed plasma heating systems and fusion engineering technologies such as blanket first wall and breeding blanket for nuclear fusion reactor development, as well as nuclear data production. Based on these technologies, we have successfully developed various ion sources-based D-D compact neutron generators and are developing a 30 MeV cyclotron-based neutron source for on-site neutron radiography service. Final construction and phase-1 licensing have been completed, and preliminary tests have demonstrated neutron yield of a 1.6x1012 n/s at 30 MeV and 0.01 mA. Under these conditions, neuron images were acquired at a resolution of 0.3 mm with an exposure time of 5 minutes.
