摘要: 核探针的概念起源于电子探针,它综合了离子束分析技术的特点,已成为很有应用前景的分析工具.本文结合上海新建成的核探针,介绍它们的原理、结构和部分应用. In concept,the scanning nuclear microprobe is similar to the scanning electron micro-probe,but has much higher sensitivity for microanalysis.The main features and the construction of thenew-built Nuclear Microprobe in Shanghai are described.It has been proved to be an ideal tool for mi-croanalysis in the fields of medical and biology,metallurg,microelectronics,archaeology and earthsciences.Its potentiality is demonstrated with examples in the applications of these fields.
