【摘要】 文章介绍２４ＭｇＯ转换成金属小球的还原技术以及同位素Ｍｇ靶的３种制备方法，即滚轧法、电阻加热法和聚焦重离子溅射法。滚轧法适用于制备＞０．１５ｍｇ／ｃｍ２的自支撑２４Ｍｇ靶，而后２种方法主要用来制作有衬底靶。更多还原

【Abstract】 The methods for preparation of isotope Mg targets are described self-supporting targets with thickness more than 0. 15mg/cm2 are prepared by rolling, while targets on carbon film with thickness less than 150μg/cm2 can be made by vacuum evaporation with resistance heating and focused heavy-ion sputtering. A special technique for conversion of 24MgO to metalic bead by reduction distillation is given.更多还原
