This presentation will investigate the impact of perturbations with different modes on different interfaces of the double shell point design. This investigation will be done with the HYDRA [2] radiation-hydrodynamics code. We will look at how the mode number influences implosion dynamics, and which interfaces are most susceptible to influence. This will help inform which surfaces must have minimized imprinting, and what the maximum allowable perturbations are.
