Construction of the first camera prototype to equip the CTA, the world’s future observatory for detecting very-high-energy cosmic gamma rays

More than a thousand physicists and astrophysicists from 27 different countries are working together to create an observatory with unsurpassed sensitivity that will serve to detect and study all sources of cosmic rays within and beyond our galaxy. While current high-performance detectors have only two to five telescopes, this global project, called CTA (Cherenkov Telescope Array), is expected to feature nearly one hundred. Each of these telescopes will be fitted with a camera, a true electronic eye, designed to measure cosmic rays entering the atmosphere. As part of the GAmma-ray Telescope Elements (GATE) Project, the first camera mechanism for this ultra-high-performance detector was recently finalized at the Leprince-Ringuet Laboratory (LLR) (École polytechnique/CNRS).
