Abstract: We introduce an ignition hohlraum 2D-simulation design method with 2D code.A design sequence,in which X-rays drive tempetature is tuned before P2 asymmetry,is put forward.Details in designing laser power is studied.It indicates that control of P2 asymmetry during trough pulse limits the maximum of filling gas density and expansion of capsule ablator can be restrained by longer drive pulse.An ignition hohlraum 2D-simulation design is given.

Key words: ICF, ignition hohlraum, 2D design, laser transport
