Spin Polarization Effects on 3He Fuel Pellets

During the 15 past years, using a volume ignition model, a computational code has been designed and gradually developed with the purpose of simulating the laser or ion projectile driven nuclear fusion. Up to now using this code various calculations have been done in different conditions for evaluating fusion gain and time dependence of temperature of fuels such as,,DDDTBH11and respectively and the results have been published in several papers. Economic fusion energy production can be based on the nuclear fusion of hydrogen isotopes deuterium and tritium. To avoid the radioactivity, another fuel must be employed. With the present technological conditions and fusion reaction cross-section considerations, seems to be the most near choice. Here, using this extended code and for the first time, we have simulated the conditions under which pure fuel pellets with different volumes and initial compressions begin to ignite. Fusion gains of more than 50 are obtained with input energies close to 5220 GJ and initial compression at 500000 times the solid state density. Also as a potential solution for low fusion gain and high initial driver energy we calculated the fusion condition for spin polarized targets. Results showed that driver energy reduction for maximum gain condition is less for less initial densities and gain increase varies irregularly for different initial conditions.
