We succeeded in making a ring-shaped target of tritium-titanium. The diameter of the ring is 150mm

the thickness of titanium layer is 1mg/cm

2

the amount of absorbed tritium is 50 Curies

and the tritium to titanium atom ratio is about 1.3~1.4. With it as a target we perfomed a test at the SINR neutron-generator and bombarded the target with 200keV deuterium. The neutron yield reached 10

n/sec at first and then was decreased 3% after fifteen minutes.
