Linac 4 has taken over from the retired Linac 2 as the first accelerator in the LHC injection chain! It has reached its first milestone to inject particles at an energy of 160 MeV and will contribute to an #LHC luminosity increase by 2021.

Last week we asked you to guess what this was… 🔎 Here we see the Experimental Linac for Surface Analysis (ELISA), a compact proton accelerator built for exhibition in #CERNScienceGateway – the only one that is ready for demonstrations to the public. ELISA is capable of performing a real Proton Induced X-ray Emission (PIXE) analysis, used in real-life to authenticate artworks, among other uses. At Science Gateway, visitors have access to hands-on experiments like PIXE and instruments like ELISA
