In a future fusion reactor like DEMOnstration reactor (DEMO) one of the main concerns is the handling of the power exhaust from the plasma, especially at the divertor. The expected power loads cannot easily be handled by traditional armor solutions based on solid materials like tungsten, especially when the effect of intense neutron bombardment is also considered. Interest in armor concepts based on liquid metals has been subsequently on the rise, as they prove to be more resilient against high, fast power loads and neutron bombardment. However, engineering solutions for those concepts are very complex, and need to be tested. For this purpose, Optimization of Liquid Metal Advanced Targets project (OLMAT) has been envisaged. The project will use the Neutral Beam Injection of the TJ-II stellarator to irradiate liquid metal targets with power densities (neutrals plus occasionally ions) relevant to DEMO steady state operation, in the range of 20 MW/m². OLMAT design will allow a series of experiments that other divertor simulator devices cannot easily perform: in-situ measurements of hydrogen retention, redeposition, vapor shielding, material fatigue, dust and precipitates effects, etc. Moreover, a high-power fiber laser will be used to simulate Edge Localized Modes in a small area, or to simulate the strike point power deposition profile.

在诸如DEMOnstration反应器（DEMO）的未来聚变反应堆中，主要关注的问题之一是如何处理等离子体中的功率排放，尤其是在分流器处。传统的基于钨等固体材料的装甲解决方案无法轻松应对预期的功率负载，尤其是在考虑到强烈中子轰击的情况下。随后，人们对基于液态金属的装甲概念的兴趣不断上升，因为它们对高，快速功率负载和中子轰击具有更强的抵抗力。但是，这些概念的工程解决方案非常复杂，需要进行测试。为此，已经设想了液态金属高级目标优化项目（OLMAT）。²。OLMAT设计将允许其他偏滤器模拟器设备无法轻松执行的一系列实验：原位测量氢保留，再沉积，蒸汽屏蔽，材料疲劳，粉尘和沉淀效应等。此外，将使用高功率光纤激光器用于模拟小范围内的边缘局部化模式，或模拟触击点功率沉积轮廓。
