Summarize this article for a 10 year old
The Hybrid Illinois Device for Research and Applications (HIDRA) is a medium-sized toroidal magnetic fusion device housed in the Nuclear Radiation Laboratory and operated by the Center for Plasma-Material Interactions (CPMI) within the Department of Nuclear, Plasma and Radiological Engineering at the University of Illinois at Urbana–Champaign, United States. HIDRA had its first plasma at the end of April 2016 and started experimental campaigns by December of that year. HIDRA is the former WEGA classical stellarator that was operated at the Max Planck Institute for Plasma Physics in Greifswald Germany from 2001 to 2013.

A unique aspect of HIDRA is that it can operate as a stellarator and as a tokamak, hence the hybrid designation. In fact, it should be possible to operate the two modes simultaneously. It operates up to 15 minutes of continuous plasma, with up to 60 minutes in the future and will concentrate on understanding the complex relationship between the plasma and materials inside the vacuum vessel of a fusion device and specifically will concentrate in understanding the complex behavior that flowing liquid metal walls, and in particular liquid lithium, have as plasma-facing materials in such devices. This makes HIDRA one of only a very few fusion devices willing to run liquid lithium as a plasma-facing material (PFM). Others include NSTX, LTX, EAST, T-11M, RFX, FTU and TJ-II.
