The European Organization for Nuclear Research (CERN) announced the creation of a unique proton accelerator ELISA. It promises to be a revolutionary tool for studying archaeological sites. This compact linear accelerator is about 1 meter long. It is capable of accelerating protons to an energy of 2 MeV. According to the authors of the project, this makes it safe for analyzing fragile artifacts such as ancient drawings and rock art pigments. One of the key advantages of ELISA is the ability to analyze in a normal atmosphere without the need for a vacuum. The device directs a proton beam at the sample, causing photons to be emitted. This allows the chemical composition of the object to be determined with high accuracy without damaging it. The team of scientists has already tested ELISA on artificial samples that mimic rock art pigments from different regions of the world. Studies have shown that the gas pedal does not harm the material. CERN has a project to create compact gas pedals that can be used directly at the site of archaeological excavations
