Description
先ず、本発明の試料ホルダー本体の長手方向の主軸材に、低熱膨張率の材料、例えばタングステンを用いることで、線膨張を軽減させ、電顕に試料ホルダーを装着した直後に発生する試料ドリフトの発生を軽減させる機構について試験を行った。
次に、試料及び試料近傍から発生するX線の漏えい防止可能な好適な材料でかつ、低熱膨張率の材料を調査した。
次に、本発明の試料ホルダーの主軸材、保持筒等に用いることが可能な材料について、特に室温変動における実熱膨張量の点から評価を行った。すなわち、特に試料ホルダー保持筒6にタングステンを用いた場合に、リンク部材10及び伝達面3の位置等の温度変化に対する安定性について調査した。すなわち、外気による微小な温度変化によるドリフトの問題も軽減できるかどうかを調べた。
