In this work, we study the interaction of accelerated protons using High Power Laser with a Boron target through Fusion Nuclear reaction and calculate the cross section of production of Carbon -12 nuclei. Recently the progress of developing Laser systems has been rising with great pace. Experimental Physics of Laser produced Plasma has been developed accordingly. Now Laser systems capable of generating High Density Short Pulses can be achieved by several ways such as chirped pulse method (CPM). This method provides Laser beams with a high density and Pulses of duration about 30-50 fs which can be used in many fields. The interaction of such laser beams with targets of light nuclei such as Boron can introduce Inertial Fusion. A Simulation calculation of the interaction of accelerated protons by High Density Laser with Boron is being elaborated in this study The following graphs are the plots for the yield of the nuclear reaction between H+ and B where the proton is the projectile accelerated by laser of energies between the range of 1 to 300 MeV towards the Boron target. These cross sections have been calculated using the program PACE-4 which is part of the Lise++ packages that is based on the Monte Carlo method. In this graph, it was found that the highest cross section was 709 mb at an energy of 2.9 MeV. There were also other Carbon isotopes found as residuals to the reaction which are demonstrated in the following graph. Further part of the study will be a comparison between the collected data and experimental data performed using similar laser systems.
