A Study Of Fast Neutron Television At The Yayoi-reactor, University Of Tokyo

Abstract

Fast neutron radiography (FNR) has been studied at the fast neutron source reactor "YAYOI" of the University of Tokyo. In the present FNR experiments, a CR39 nuclear track detector (it's called CR39 imaging film or CR39 film in this report) has been applied successfully. In order to obtain the prompt and/or real-time imaging results, a fast neutron television system (FNR-TV) has been developed, which has shown the first data as for the fast neutron television imaging technique in the world.
