Comparison of Energy Gain in Laser and Magnetic Fusion

In this paper the zero-dimensional nonlinear transport model is applied to obtain the energy and the densities of deuterium and tritium fuel ions, as well as the alpha-particles in fusion reactor for laser and magnetic confinement methods. In this work D-T fuel pllets with. KrF laser is used in laser confinement and ITER paremeters are considered for magnetic confinement fusion. In order to densities of these ions are considered separately. Also, unlike the previous works which used impurity injection to mitigate thermal excursions, this design exploits the ability to modulate the DT fuel mix to control the plasma heating. By moving the isotopic mix in the plasma away from the optimal 50:50 mix, the reaction rate is moderated and the alpha-particle heating is reduced to desired levels. The zero-dimensional simulation study is presented to compare the energy gain in two states of laser and magnetic confinements.
