An Overview of Spin Polarization Effects on Initial Needed Energy and Fusion Gain for 3He Fuel

Up to now, various calculations have been done for evaluating fusion energy gain and time dependence of temperature of compressed pellets such as DT, D3He, DD, H11B and 3He3He in the absence of magnetic fields. Experimental results and their comparison with the results of simulations based on central spark ignition model and volume ignition model, prove the accuracy of our computational code. Industrial usage of fusion energy needs an increase in fusion gain and a reduction in driver energy. So that here, using volume ignition model for nuclear spin polarized pellets (in a magnetic field), the energy gain is calculated. The comparison between results associated with the polarized and non polarized fuel, shows that spin polarization is an effective method for reducing the initial needed energy for ignition (up to 35%) and increasing the fusion gain.
