ANAIS-112 is a dark matter particle detector at the Canfranc Underground Laboratory in Spain. It is similar to DAMA/LIBRA, and among its intentions is to attempt to reproduce the announced DAMA-LIBRA results. The detector consists of carefully shielded scintillators of sodium iodide crystals (NaI) doped with thallium expected to interact with WIMPs, with a surrounding liquid scintillator, along with photomultiplier tubes to sense the interactions. The aim is to detect a variation in the number of interactions that is proportional to Earth's speed passing through the Milky Way's dark matter, which would vary over the course of Earth's orbit around the Sun. Other types of particle interactions would be less likely to show this particular pattern.
As of 2023, ANAIS-112 data does not tend to reproduce the DAMA-LIBRA's results.
