Upgrade ion accelerator

升级后的离子注入机“罗密欧”将使相关研究小组能够开展新的注入实验光谱。重点将是对现代(量子)材料和纳米结构的光学性质进行有针对性的修改。这包括在半导体中实现基于镧系元素或过渡金属的光中心，通过操纵介质的介电函数，到在钻石和2D材料中合成新的量子发射器。这些主题是许多研究项目的中心，以及光学位置耶拿的两个协调的DFG研究项目的中心，一个合作研究中心(SFB 1375“NOA”)和一个国际研究生院(IRTG 2675“Meta-Active”)，因此这些项目将随着请求的升级而得到显著加强。植入器的升级将带来三个新功能。(A)将购买并整合一个配有适当电源的溅射离子源。这将使许多以前无法接触到的新元素产生高离子电流。其中尤其包括高熔点(过渡)金属和镧系元素。(B)即将购买的新高压终端将配备新类型的透镜，以便能够获得低离子能量。再加上溅射源，就有可能用元素周期表的几乎所有元素以高离子通量照射整个相关能量范围内的样品。这种灵活性将为未来所有工作组开辟新的研究领域。(C)该系统将完全由电脑控制。这一新功能不仅将显著提高效率和作业时间，还将实现元素和能量之间的快速切换，从而实现以前无法实现的复杂元素和深度剖面。与其以高昂的成本购买新的植入器，不如继续使用现有植入器的可用部件(加速管和束流线)。该系统的主要使用将由弗里德里希·席勒大学(FSU)耶拿的四个小组按比例进行，他们的总部设在物理和天文学学院。然而，原则上，该系统将向金融服务联所有群体提供，就像过去的情况一样。特别是，升级后的植入器将使使用它的小组之间进行各种新的跨学科合作。总体而言，位于光学和材料科学两个重点研究领域交界处的圣母大学耶拿的科学光谱将大大扩大和加强。

The upgrade of the ion implanter "Romeo" will enable the involved research groups to carry out a new spectrum of implantation experiments. The focus will be the targeted modification of the optical properties of modern (quantum) materials and nanostructures. This ranges from the realization of light centers based on lanthanides or transition metals in semiconductors, via the manipulation of the dielectric function of dielectrics, to the synthesis of new quantum emitters in diamond and 2D materials. These topics are at the center of many research projects as well as two coordinated DFG research programs at the optics-location Jena, a collaborative research center (SFB 1375 "NOA") and an international graduate school (IRTG 2675 "Meta-Active"), so that these will be significantly strengthened with the requested upgrade. The implanter upgrade will result in three new features. (a) A sputter ion source with appropriate power supplies will be purchased and integrated. This will enable high ion currents of many new elements that were previously inaccessible. These include, in particular, high-melting (transition) metals and lanthanides. (b) The new high-voltage terminal to be purchased will be equipped with new types of lenses, so that low ion energies will become accessible. Together with the sputter source, it will then be possible to irradiate samples over the entire relevant energy range with almost all elements of the periodic table at high ion fluences. This flexibility will open up new fields of research for all working groups in the future. (c) The system will be fully computer controlled. Not only will this new feature significantly increase efficiency and operation time, but it will also enable fast switching between elements and energies, allowing for complex element and depth profiles that were previously unfeasible. Instead of purchasing a new implanter at high costs, usable components of the existing implanter (acceleration tube & beam line) should continue to be used. The main use of the system will be proportionately carried out by four groups from the Friedrich Schiller University (FSU) Jena, which are based at the Faculty of Physics and Astronomy. In principle, however, the system will be made available for all groups of the FSU, as was already the case in the past. In particular, the upgraded implanter will enable various new interdisciplinary collaborations between the groups using it. Overall, the scientific spectrum of the FSU Jena at the interface between the two focal research areas on optics and materials science will be significantly expanded and strengthened.
