Research Abstract

The purpose of this study is to create a new concept of sophisticated fusion neutron measurement system based on optical fiber sensing technique, where deposited energy and position of fusion neutrons incident onto a network consisting of organic optical fibers and scintillators with different characteristics are measured three-dimensionally and simultaneously from light propagation time, light absorption rate and solid angle subtended by light emission point in the network components.
We have designed and partially manufactured the prototype system for experimental demonstration of their basic performances.
Main achievements in this study are summarized as follows :
(1)A simple and compact fusion neutron measurement system which can obtain energy and incident direction (or profile) of neutrons simultaneously has been devised and experimentally demonstrated by using multistage plastic scintillating fibers combined with a pair of position sensitive photomultipliers.
(2)A fusion neutron image sensor with a large sensitive area has been devised and experimentally demonstrated by combining organic liquid scintillator with wavelength shifting fibers.
(3)The simulation program has been developed to estimate the above detector performance based on the experimental results and used to improve and/or optimize the detector system design.
(4)These results have been applied to conceptual design proposals for an ITER-like fusion plasma diagnostics, in particular for new concept of fusion neutron profile monitors.
