The Tandetron Laboratory of the Nuclear Physics Institute of the Czech Academy of Sciences is equipped with five beam lines associated with a 3 MV tandem electrostatic accelerator model 4130 MC from High Voltage Engineering Europa B.V. This accelerator is coupled with two duoplasmatron sources and a single sputter ion source and provides ions from hydrogen to gold. One of these lines is a nuclear microbeam facility, utilizing ion beams of micro- and sub-micro sizes for materials research by use of particle induced x-ray emission spectroscopy, particle induced gamma emission, Rutherford back-scattering spectroscopy, and scanning transmission ion microscopy methods as well as for ion beam writing. The major advantage of the presented microprobe is a possibility of 3D structure creation not only in polymer materials using light ions but also in other materials such as glass, ceramics, etc. by use of heavy ions. The focusing system allows focusing of charged particles with a maximum rigidity of 11 MeV amu/q. The usual resolution in high and low current modes is 2 × 3 µm for a 100 pA and 0.3 × 0.5 µm for the 2000 ions/s of 2 MeV protons, respectively. A detailed facility description is given in the paper. The applications of focused beams of heavy ions as well as examples of light ions utilizing are also presented in the article.
捷克科学院核物理研究所的Tandetron实验室配备了五条束流线，与一台来自欧洲高压工程公司的3 MV串联静电加速器4130 MC型相连。该加速器与两个双等离子体源和一个溅射离子源耦合，可提供从氢到金的离子。其中一条束流线是一个核微束装置，利用微米和亚微米尺寸的离子束，通过粒子诱导X射线发射光谱法、粒子诱导γ发射、卢瑟福背散射光谱法和扫描透射离子显微镜方法进行材料研究，以及用于离子束写入。所介绍的微探针的主要优点是不仅可以使用轻离子在聚合物材料中创建三维结构，还可以通过使用重离子在其他材料（如玻璃、陶瓷等）中创建三维结构。聚焦系统能够聚焦最大刚度为11 MeV amu/q的带电粒子。在高电流和低电流模式下，对于100 pA的电流，通常分辨率为2×3 µm；对于2 MeV质子每秒2000个离子的电流，分辨率为0.3×0.5 µm。该论文给出了详细的装置描述。文章还介绍了重离子聚焦束的应用以及轻离子利用的实例。
