Experiments were performed on Nova at Lawrence Livermore National Laboratory to study the ablation and condensation process of National Ignition Facility (NIF) first wall materials. Plates of candidate first wall materials (SiO{sub 2}, B{sub 4}, and Al{sub 2}O{sub 3}) were exposed to x-rays from hohlraums in the Nova chamber. Ablated material was collected and measured on a receiving plate which was blocked form direct x-ray exposure. This article presents the results form these experiments and comparisons with predictions from numerical simulations The net condensation flux was calculated using the TSUNAMI code, which was modified to incorporate the feature of condensation boundaries.
