Description:
Neutron yields have direct correlation with the energy of incident deuterons in experiments of laser deuterated target interaction [Roth et al. , Phys. Rev. Lett. 110 , 044802 (2013) and Higginson et al. , Phys. Plasmas 18 , 100703 (2011)], while deuterated plasma density is also an important parameter. Experiments at the Shenguang II laser facility have produced neutrons with energy of 2.45 MeV using d (d, n) He reaction. Deuterated foil target and K-shaped target were employed to study the influence of plasma density on neutron yields. Neutron yield generated by K-shaped target (nearly 10 6 ) was two times higher than by foil target because the K-shaped target results in higher density plasma. Interferometry and multi hydro-dynamics simulation confirmed the importance of plasma density for enhancement of neutron yields.
