Status of development and planning activities on CANS in Korea

Abstract

This report reviews the overall status of the development and planning activities of compact accelerator-based neutron sources in Korea. For the last decade, the demand for the technology development and application of CANS has significantly increased, and becomes widely accepted by the science, engineering and industry sectors. Since the first technical workshop focused on CANS under the support of the Korea Nuclear Society in fall 2016, there have been numerous efforts to launch projects by several groups. Although unsuccessful, two CANS projects were newly launched in 2020. One is the 30-MeV cyclotron-based neutron source for industrial neutron imaging at the Korea Atomic Energy Research Institute (KAERI), and the other is the BNCT technology development at the Korea Institute of Radiological & Medical Sciences. A project proposal for an expansion of the proton LINAC facility at KAERI to 200 MeV for semiconductor irradiation testing through the produced neutron field is now almost complete and will be submitted to the government funding agency for review. The CANS project for BNCT based on the proton LINAC developed by the Dawonsys consortium is briefly described. The new neutron source based on electron LINAC is prepared by the Pohang Light Source laboratory, and the initial consideration and application targets are also described. A new strategic plan for national R&D on radiation technology and the enforcement of its infrastructure is still under way, and a more systematic approach to the development and application of neutron sources will be implemented through the strategic planning.

The Anti-Tumor Effect of Boron Neutron Capture Therapy in Glioblastoma Subcutaneous Xenograft Model Using the Proton Linear Accelerator-Based BNCT System in Korea

“…Neutron irradiation was conducted by DM-BNCT. Details about the accelerator and beam parameters can be found in Lee et al as well as an overview of the A-BNCT system in Korea [ 24 , 25 ]. To accurately measure the thermal neutron fluence, we used two methods: one was the foil activation method, and the other was the Eu:LiCAF scintillation detector.…”

Advances of LINAC-based boron neutron capture therapy in Korea

“…The first A-BNCT facility in Korea was LENS10 developed by the DawonMedax company [35,36]. The acronym LENS10 came from its being a "10-MeV linacbased epithermal neutron source. "…”

Summary of the 3rd International Workshop on Gas-Dynamic Trap based Fusion Neutron Source (GDT-FNS)

“…Here, neutron wall loading was used the a reference value as 1 MW m −2 , which can be 10 dpa/fpy for structural material. For CANS, cyclotron-based neutron source has been considered and its feasibility has been investigated with the existing 30 MeV cyclotron at KAERI, which is used for radio-isotope production and newly used for developed neutron radiography currently [51][52][53]. For V-FNS, conceptual design of spherical tokamak (ST) based FNS has been performed.…”
