Variance of DD-neutron yield in laser fusion experiments
Original language description
This contribution deals with experimental observations of the yield of DD fusion in deuterated plastic targets irradiated by 300-ps 3-TW laser system PALS. To perform the analysis of variance for neutron yield values, Yn, in the range of 105- 109observed in a relatively narrow range of laser energy E from 500 - 700 J, the observed yield values were included in a neutron-yield - laser-energy (Yn-E) diagram showing general trends in the energy yield scaling Yn(E). This dependence is characterized by a power law, Yn= Q E1.65, where Q is the parameter reflecting possible dependence on the pulse duration, laser intensity, laser contrast ratio, focal geometry, target structure, etc. [1]. The analysis we present shows that, despite shot-to-shot fluctuations, the variance of Q values from 14 - 5.2x104for the narrow range of laser energy obtained in PALS experiments can be elucidated by the influence of some nonlinear processes affecting ion acceleration.
