日本原子能研究所近来研制成功了能观察材料在受到离子束照射时表面发生的变化的电子显微镜,并由日本电子公司将其商品化。该装置由电子显微镜和离子枪构成。使用时,一边将高能量离子打入固定在显微镜上的试样上,一边用电视摄像机拍下、观察它的形貌。用于照射的离子有氩、氧、氮、氦、氢等。试样表面每平方米能承受6×10~(14)/s高密度离子。原有的电子显微镜只能观察照射后的试样,依此来推断照射过程中发生了什么样的变化;而上述新装置,不必借助于想象,即可知道照射时的动态过
Japan Institute of Atomic Energy has recently succeeded in developing an electron microscope that can observe changes in the surface of a material as it is exposed to ion beams and commercialize it by Nippon Denshi. The device consists of an electron microscope and an ion gun. Use, while high-energy ions into the fixed sample on the microscope, while using a video camera photographed to observe its appearance. The ions used for irradiation are argon, oxygen, nitrogen, helium, hydrogen and the like. The sample surface can withstand 6 × 10 ~ (14) / s high density ions per square meter. The original electron microscope can only observe the irradiated sample, so as to deduce what happens in the irradiation process; and the new device, without the aid of imagination, you can know the dynamic during irradiation
