A performance study of a high gain target for heavy ions beam fusion
Through numerical simulations, a target has been designed to produce an energy gain close to 100, when irradiated with the appropriate heavy ion beam. The thermo-fluid numerical studies for the dynamical behaviour of this target, made with the 1D code CLIFF and with the 2D code COBI-1, show some interesting features: the fusion fuel ignites almost contemporaneously and ignition occurs only for asymmetries in the beam intensity between pole and equator of less than 6%. Radiation losses play an important role when asymmetries are present. In fact, when radiation transfer is switched-off in the code, ignition has been observed even for asymmetries of 10%.
