Development of Fusion Neutron Pinhole Imaging using Nuclear Emulsions for Energetic Ion Diagnostics

A compact neutron pinhole camera using nuclear emulsion has been developed as a neutrone mission profile monitor for energetic ion diagnostics in fusion plasma. We measured point-spread function of the neutron pinhole camera consists of a pinhole collimator made of tungsten alloy and stacked nuclear...

Description
Summary:A compact neutron pinhole camera using nuclear emulsion has been developed as a neutrone mission profile monitor for energetic ion diagnostics in fusion plasma. We measured point-spread function of the neutron pinhole camera consists of a pinhole collimator made of tungsten alloy and stacked nuclear emulsions. Using a high-speed, automatic readout and recognition of recoiled proton tracks, point-spread function for 14 MeV neutron was clearly obtained.
