Abstract
Ion-hose instability growth of the 2-mus electron beam pulses will be studied during the Phase-II commissioning of the DARHT-II Facility. We have done simulations in support of the experiment using pressure profiles estimated for different pumping arrangements along the accelerator. Results of these simulations are reported in this paper and compared to simulation results reported previously using constant pressure profile along the accelerator. Good agreement is found.
