| Popis: | In the present work, the effect of the external magnetic field of on the energy deposition of the relativistic electrons into high density fuel of in fast-shock ignition concept has been investigated by using the Geant4 simulation toolkit. In our simulation model, two types of the energy distribution function including exponential energy distribution and quasi-two temperature energy distribution function, for relativistic electrons with an initial kinetic energy of were considered. The results of simulations in the presence of an external magnetic field show that the dynamics of the relativistic electrons are strongly affected by the external magnetic field which results in the optimum energy transfer into the fuel. The comparison of the results indicates that the optimal energy deposition is obtained for the density of in the presence of a magnetic field of about with an ignitor laser wavelength of and laser intensity of . It can therefore be concluded that by increasing the external magnetic field of , the energy deposition rate increases slowly. |
