The present research was undertaken to manufacture an ion beam microsectioning apparatus for precise measurements of neutron radiation-enhanced diffusion in metals and alloys. The neutronirradiated diffusion sample is sectioned by the ion-beam microsectioning apparatus and deposited onto Kapton films. After the deposition, the activity from the deposited Kapton films is measured by a scintillation counter to know the diffusion-penetration profiles. The apparatus was manufactured successfully and fully operated to measure the diffusion penetration profiles up to a depth of 200 nm.Several irradiation experiments were performed at the JMTR. The aluminum sample on which iron film of 10 nm was deposited was capsuled into aluminum can under a vacuum to prevent oxidation in irradiation. Radiation diffusion runs were carried out for 533 hr. at 400C and for 168 hr. at 200C. After irradiation the samples were sectioned by the ion-beam microsectioning apparatus and diffusion penetration profiles were determined with high precision.

本研究的目的是制造一种离子束显微切片装置，用于精确测量中子辐射在金属和合金中的扩散。用离子束显微切片仪对中子辐照扩散样品进行切片，并将其沉积在卡普顿薄膜上。沉积后，用闪烁计数器测量沉积的卡普顿薄膜的活度，以了解扩散-穿透曲线。该仪器研制成功，运行正常，可测量深度达200 nm的扩散渗透曲线。在JMTR进行了几次辐照实验。将镀有10nm铁膜的铝样品真空封装在铝罐中，防止辐照氧化。辐射扩散运行533小时。在400摄氏度下加热168小时。在200 c。辐照后用离子束显微切片仪对样品进行切片，高精度地测定了扩散穿透剖面。
