TW）を用いたワイベルフィラメント計測実験を提案する。本提案ではサブピコ秒、数十nmでフィラメント構造を可視化する必要があり、SACLAによるX線小角散乱を計測する。その予備実験として、今回、ワイベルフィラメントを模擬したシリコンロッド集合体ターゲット（ロッド直径500 nmの円柱が1000 nm間隔に多数配置されたターゲット）に高強度レーザーを照射し、その時間発展をX線小角散乱によって計測した。","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期,
