研究了在Ｃｙｃｌｏｎｅ－３０回旋加速器上利用核反应６９Ｇａ（ｐ，２ｎ）６８Ｇｅ制备无载体６８Ｇｅ的工艺条件，并研制成生产６８Ｇｅ的半自动化装置，提出了一种固体靶制备方法，靶材料为Ｇａ４Ｎｉ合金，质子能量Ｅｐ＝２０ＭｅＶ，辐射过的靶子用硝酸溶解，然后通过液液萃取系统分离６８Ｇｅ，经热实验验证６８Ｇｅ回收率＞９１％。
The conditions for the preparation of carrier-free 68Ge by nucleation 69Ga (p, 2n) 68Ge on a Cyclone-30 cyclotron were studied and a semi-automatic device for producing 68Ge was developed. A solid target preparation method was proposed. The target material was Ga4Ni alloy , The proton energy Ep = 20MeV, the irradiated target was dissolved with nitric acid, and then the 68Ge was separated by liquid-liquid extraction system. The thermal recovery rate of 68Ge was> 91%.
