Introduction of OKTAVIAN
Welcome to OKTAVIAN!
OKTAVIAN was built at Osaka University and has been operated since 1981 as an intense deuterium-tritium (D-T) neutron source at 1.5-ns pulses of 103 D-T neutron/pulse or as the maximum continuous neutron source of 3×1012 D-T neutron/s. OKTAVIAN consists of a high-current deuteron beam accelerator for D-T neutron production. Many fusion neutronics experiments have been carried out for the fundamental study of D-T fusion neutron transport characteristics.
