Experiments have been conducted to compare the re-emission from foam gold with a 0.3 g cc−1 density and solid gold in a SGIII prototype laser facility. Measurements of the re-emission x-ray flux demonstrate that emission is enhanced by the low density foam gold compared to the solid gold under the same conditions. The emission fraction increases with time and is concentrated on soft x-ray flux between 0.1–1 keV. The simulation results with Multi 1D agree with the experimental results. There are potential advantages to using foam walls for improving the emission and soft x-ray flux in hohlraums.

フォーム金(密度0.3 g cc⁻¹)と固体金からの再放射を比較する実験が、SGIII原型レーザー施設において実施された。再放射X線フラックスの測定により、同一条件下において、低密度フォーム金からの放射が固体金と比較して増強されることが実証された。放射割合は時間とともに増加し、0.1〜1 keVの軟X線フラックスに集中している。Multi 1Dによるシミュレーション結果は実験結果と一致している。ホーラムにおいて放射および軟X線フラックスを向上させるためのフォーム壁の使用には、潜在的な利点がある。
