Description

A neutron optics design has been conducted for a neutron magnetic microscope that utilize a Wolter type I multilayer supermirror for the purpose of magnetic fields imaging in magnetic materials. Ray trace simulation was performed for a magnifying imaging optical system with a magnification rate of 12.5 times. Based on classical model of Lamor precession, depolarization due to magnetic domains was simulated, and the effect of slope errors on the Wolter mirror created by the replica method on the spatial resolution of the microscope was investigated. As a result, reference data about the shape error required to obtain spatial resolution on the order of micrometers was obtained. (author)

Abstract (Japanese)

磁性体中の磁場イメージングを目的として、Wolter I型光学系に多層膜スーパーミラーを適用した中性子磁気顕微鏡の光学設計を行った。拡大率12.5倍の拡大結像光学系について、軌跡シミュレーションコードを用いて、偏極中性子の磁性体試料によるdepolarizationの解析、レプリカ法で作製されるWolterミラーの形状精度が顕微鏡の空間分解能へ与える影響の検討を行った。その結果、マイクロメートルオーダーの空間分解能を得るために必要な形状精度に関する知見を得た。(著者)
