Abstract:
The principle of thermal neutron converting to 14MeV neutron is briefly introduced.A calculation and analysis model for 14MeV neutron effective production is established.The probability for the thermal neutron absorbed by 6Li and for T not leaked in
6LiD are calculated.The cross sections for T and D fusion reaction and T and 6Li fusion reaction are proposed,and the curves for the effective yields of 14 MeV neutron with the thickness of
6LiD is given.The results show that when
6LiD thickness is between 0 and 0.5mm,the effective yields of 14MeV with
6LiD thickness almost augment linearly,and then gradually remain at a set value;and when
6LiD thickness is 0.7mm and 1.0mm,the effective yields of a thermal neutron converted to 14 MeV neutron is 3.18×10
-4 and 3.53 ×10
-4,respectively.
