On the rate of energy deposition by an ion ring velocity beam

Using a novel three-dimensional electromagnetic hybrid code, XHYPERS, we simulate the generation of lower oscillations in magnetized plasma by heavy ion beam with ring-shaped velocity distribution over much longer periods time compared to previous simulations. We introduce phenomenological (effective) electron damping represent induced scattering lower-hybrid waves whistlers and loss energy through whistler propagation out turbulent region. demonstrate effective be crucial factor increasing efficiency deposition an ring into turbulence investigate extraction as function rate mass ratio.
