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.

离子注入机“罗密欧”的升级将使相关研究小组能够进行新的注入实验谱。重点将是现代（量子）材料和纳米结构的光学性质的有针对性的修改。这包括从半导体中基于镧系元素或过渡金属的光中心的实现，通过对介电函数的操纵，到在金刚石和2D材料中合成新的量子发射体。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DFG研究计划，一个合作研究中心（SFB 1375“NOA”）和一个国际研究生院（IRTG 2675“Meta-Active”），因此这些将通过要求的升级得到显着加强。升级后将带来三个新功能。(a)将购买并集成一个配有适当电源的溅射离子源。这将使以前无法获得的许多新元素的高离子电流成为可能。其中特别包括高熔点（过渡）金属和镧系元素。(b)新购买的高压终端将配备新型透镜，以便可以使用低离子能量。与溅射源一起，它将有可能在整个相关能量范围内以高离子通量照射几乎所有元素周期表中的元素。这种灵活性将为今后所有工作组开辟新的研究领域。(c)该系统将完全由计算机控制。这一新功能不仅将显著提高效率和操作时间，而且还将实现元素和能量之间的快速切换，从而实现以前不可行的复杂元素和深度剖面。与其以高成本购买新的加速器，不如继续使用现有加速器的可用组件（加速管和束流线）。该系统的主要用途将由耶拿弗里德里希·席勒大学（FSU）的四个小组按比例进行，这四个小组位于物理学和天文学学院。但是，原则上，该系统将向前苏联的所有团体提供，就像过去一样。特别是，升级后的光学仪器将使使用它的小组之间能够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之间的FSU Jena的科学光谱将得到显着扩展和加强。
