National Research Infrastructure Roadmap 2018 for Hungary. For Hungary, the Extreme Light Infrastructure Attosecond Light Pulse Source (ELI-ALPS) facility has particular importance: it is a major con- tribution to laser research and can open new ways for physics, chemistry, materials science and medical biology. The facility, which started operation gradually in late 2017, is mainly used for basic research but will also contribute to applied research and, as a spillover effect, to industrial application. In addition to the ELI-ALPS, there are several other research infrastructures in Hungary. These lower cost RIs can be fi- nanced from national funds and are normally not considered as unique facilities, still, they are essential for Hungarian researchers. To use the large scale European RIs and join the international scientific networks around them, Hungary needs well-equipped domestic RIs.
