Description

図6Bは、別の例における回転式アノードアセンブリ150を示す。図6Bに示す例において、回転式アノードアセンブリ150の角速度は、一定値ωである。この例において、液体金属アノード材料153に作用する重力に加えて、遠心力が、液体金属アノード材料153に作用する。その結果として、液体金属アノード材料153は、また、回転軸線Aに平行な方向において、回転式アノード支持構造151の形状に適合する。回転式アノード支持構造151は、液体金属アノード材料153が、角速度がゼロでないときに回転式アノード支持構造151と接触した状態のままに拘束されるように成形されている。言い換えると、角速度がゼロでないとき、回転式アノード支持構造151は、液体金属アノード材料153が、溢れず、失われないように成形されている。
一例では、測定データ124は、試料の測定されたX線応答についての表示を含む。検出器123の表面で測定されたX線応答の分布に基づいて、試料101でのX線ビーム108の入射位置及び領域が、計算システム130によって決定される。一例では、パターン認識技術が、計算システム130によって適用されて、測定データ124に基づいて、試料101上でのX線ビーム108の入射位置及び領域を決定する。それに応じて、計算システム130は、電子光学部品104及びX線光学部品106のうちの任意のものへのコマンド信号を発生させることにより、入射X線照明ビーム108の向き及び形状を変える。
