Outline of Final Research Achievements

A sealed discharge plasma fusion neutron source facility (IECF) witch secures the tritium safety has been developped for the use of tritium gas. The operation with the D-T mixed gas of the mixture ratio, 93%:7% has achieved 8 times more neutrons than D gas.The multiplication agreed with the theoretical estimation.The use of D-T fuel gas with the mixture of 50%:50% by the discharge voltage 70kV and current 60mA is anticipated to produce ten to the 9th power(1/sec) neutron. The experiments verified the D-T fuel IECF can be a neutron source for radiograph, basic research of the cancer therapy,inspection of explosives and landmine detection etc.
