Experimental study on the performance of an epithermal neutron flux monitor for BNCT

The performance of an epithermal neutron (0.5 eV < E-n < 10 keV) flux monitor designed for boron neutron capture therapy (BNCT) was experimentally studied by using a prototype monitor in an appropriate neutron field at the intense deuterium-tritium neutron source facility OKTAVIAN of Osaka University, Japan. It was convinced from the experimental results that the developed monitor worked well and the epithermal neutron fluxes in BNCT neutron sources can be measured within 5% by the monitor.
