Abstract

The Nagoya University Accelerator driven Neutron Source (NUANS) is constructed at the main campus of the Nagoya University. The electrostatic accelerator is used with the maximum proton energy and intensity of 2.8MeV, 15mA(42kW) respectively. Two neutron beamlines are designed at NUANS. The BL1 is dedicated to BNCT development. The BL2 is designed for research and development for neutron devices and neutron imaging. The neutrons used for the BL2 are generated by using the (p, n) reaction from a thin beryllium target. We constructed a compact target station for the BL2 and measured the neutron transmission image.

Highlights

  • Neutron is a very good probe to investigate the inner structure of materials

  • Large neutron facilities like J-PARC MLF and SNS have been constructed in this decade, and ESS facility is under construction

  • It is very important to consider what you can do with Compact Accelerator-driven Neutron Source (CANS) and what you should do with large neutron facilities

Summary

Introduction

Neutron is a very good probe to investigate the inner structure of materials. Large neutron facilities like J-PARC MLF and SNS have been constructed in this decade, and ESS facility is under construction. It is very important to consider what you can do with CANS and what you should do with large neutron facilities. We can use these CANS for BNCT(Boron Neutron Capture Therapy), neutron imaging, device development and so on. Nagoya University has constructed CANS using an electrostatic accelerator, Nagoya University Acceleratordriven Neutron Source (NUANS)[2,3,4]. Two neutron beamlines are designed at NUANS. In both beamlines, neutrons are provided by bombarding a high current proton beam to a lithium and beryllium target, respectively. The proton beam hits the neutron generation target
