for designing a neutron source

the neutron yield of T(d

n)4He reaction at 120 keV of incident deuteron energy is calculated by a mathematical method.The neutron yield by the incident beams of different percentages of D+and D2+was studied.The neutron yield increase effectively with the percentage of D+and decreases with increasing percentages of D2+.The effects of different target materials and components on the neutron yield are studied.The neutron yield is in proportion to the content of the tritium and in inverse proportion to the target atomic mass.Parameters of the ion source and the thick target are analyzed for improving performance of the neutron source.Effects of the oxide layer or film coatings in surface of the titanium tritide film on neutron yield are calculated

too.The results are compared with experimental results.A novel target design is introduced and its feasibility is studied.
