Dynamical thermal noise effects on the p11B fusion plasma utilizing KrF laser

In this paper, we study the effects of thermal noise on the time evolution of energy and particle densities in burning plasma for inertial fusion with p11B fuel that inertial confinement fusion in this work is performed with KrF laser. The fusion reaction takes place in a plasma of proton and boron-11 heated to millions of degrees. At this temperature, the thermal noise has significant effects not considered in equations that have been solved so far, and this effect is intended for the first time in this work. A suitable thermal noise term is added to a set of four coupled equations including particle and energy balance equations. These equations are solved simultaneously by numerical methods. The results of the calculations for fusion power, particles densities, fusion energy density, and quality factor in two states without noise and with noise showed that in the conditions where the thermal noise is considered, the above parameters and the quality factor are increased, and improves system performance, and also satisfies Stefan–Boltzmann's law for the intensity of fusion energy.
