Özet
The energy distributions and electromagnetic emissions of deuterium ions and electrons in an inertial electrostatic confinement (IEC) unit are reported for low and moderate magnetic field cases. The IEC device has a central wire system inside the grid system of the chamber for the production of the azimuthal magnetic field. The real-time simulations are performed by time integration method by using a finite difference method (FDM) for the physical geometry of device. It is observed that the field induces helical trajectories on the particles especially at the central region where the magnetic force is maximized in a fully ionized Deuterium media. The results prove that the particles have rich dynamics in terms of their trajectories. The effect of negative potential and particle particle interaction play important roles to determine the trajectories even for low number of ions and electrons. Ion temperatures are calculated as T-i = 6.9 keV after 6 mu s for low field case and T-i = 1.517 MeV after 22 mu s for medium field case. (C) 2017 Hydrogen Energy Publications LLC.
